...oritize LAN traffic that is destined to the other LAN based on the type of traffic that it is (ICMP, RDP, RFB, SMB, etc) before it is encapsulated. Once the traffic has been encapsulated I''d like to QoS / Prioritize the ESP traffic that is destined to the other LAN''s globally routable IP before any other internet traffic goes out. This later part is not the problem, just the former part. My network layout(s) are below for those of you that will be asking: Lan A: - 172.30.12.x/24 subnet - 172.30.12.1-250 client systems and the likes - 172.30.12.254 is the default gateway...

...'m rate limiting and prioritizing traffic upstream of a slow wan link using htb, classic wonder shaper type stuff. I''m using the following command for traffic that does not match any of my defined filters: tc qdisc add dev eth0 root handle 1: htb default 50 It appears that local, non-routable traffic like arps and igmp are being snared by this and end-up queued in the lowest priorty queue. I was surprised that non-IP traffic would be effected by IP traffic control. How do I prevent this local, non-routable traffic from being queued? Since it''s local, I just want it to go at li...

Hi, We have configured several xen guest OSes on a server running SLES10. The physical server is a Sun 4200 with 3 NICs installed, configured, and working. Each of the xen guest OSes have three virtual nics, configured for RAC, Interconnect, and public IPs as follows; eth0 - public (routable and registered in DNS) eth1 - private (not routable, uses a seperate network subnet for 10.10.0.XXX) eth2 - RAC (routable and registered in DNS) Right now, all of the guest OS nics are being connected to eth0 of the physical host, using xenbr0. I know that an entry needs to be made in /etc/xe...

...rvers from parallel to the DMZ (outside the firewall, directly connected to I-net) to inside DMZ. The default gw for these servers was the DSL router(bridge) of my ISP. What should be the default gw (for the hosts inside the DMZ), when hosts are inside the DMZ now - still the DSL router (external routable IP Address) or the network interface for the DMZ zone - 10.10.200.1 (non-routable one)? I searched the documentation, but couldn''t find an answer. Appriciate your help. Thank you in advance. Visit my Web Site: http://www.dbaclick.com Tons of Oracle DBA''s scripts, articles,...

Greetings all! I just got a colocated server space and the ISP has given me an IP address and a routable /29 subnet. Here''s a partial snippet of the info they gave me (with the real addressess changed for privacy) ==== WAN Address Customer IP Address : 100.0.33.14 Netmask : 255.255.255.248 Broadcast Address : 100.0.33.15 Default Gateway : 100.0....

Dear all, Has anyone experienced this whilst running DRBD over eth1 between two CentOS 5.7 servers? eth1 is a private IP address, unroutable. eth0 is the public address. CentOS will reply sometimes once every 3 days or every 14mins~ saying "My public IP is on eth1" to arp requests when it's not, it's eth0. This freezes traffic and causes issues. We've looked at arp* /etc/sysctl.conf etc. and arptables, but wonder...

Hello, All is fine when I run in development mode with rails + lighttpd. I''m using the lighttpd.conf file that is auto-generated by Rails. Works just fine in developemtn mode. When I swith to production mode and use my externally routed domain name lighttpd refuses to bind to the address. I know the address works since I run a mail server behind it. I can ssh to it, etc. I have

I am experimenting with kvm on a quad x86_64 running CentOS-5.5. I have created my first virtual guest and it seems to run fine. Now I wish to assign that particular guest to a fixed, public IP address. There seems to be at least two ways to proceed and I am soliciting comments on the preferred approach. In the first instance I can use brctl to create a bridged 'shared physical device'

...ve SetOutputFilter fixplaylistport </Location> </VirtualHost> And it works like a charm, and allows us to benefit from the HTTP 1.1 "Host" header, and use it in a virtual host. The filter simply rewrites the listening URL served by the Icecast pages to routable addresses and routable ports. I would agree this is not the most elegant way to do, but we don't have a choice here. Cheers ! Le 23/05/2014 10:59, "Thomas B.

...nux Sysadmin, but I haven''t done much in the way of routing. Due to a decision made by my higherups, I need to jam a computer between my ISP and my LAN to do bandwidth throttling. My current setup: 1 Crappy Cable Modem (7Mb/768Kb connection) with a static IP. 4 servers (all have static, routable IPs) - One of which is running NAT/DHCP (2 NICs) for 6 workstations (All using DHCP) I have 1 spare routable IP. My current setup has the cable modem plugged directly into my LAN. But it ends up this modem doesn''t do intelligent traffic/bandwidth management. I need a way to throttle...

I been running shorewall with out any problems for several months. But I''ve now run into a problem. Hopefully this will be enough information. I''m running shorewall version 1.4.8. On Fedora core 1. Coming into my location I have a T1. I have 5 internet routable IP''s. I''m currently using one as my default internet connection. My ISP''s router is actually assigned all of my internet routeable IP''s and they forward the traffic to in internal ethernet segment. On this segment i have my firewall. The firewall has 3 inter...

...great reasons, but I have one reservation. By using private addresses with NAT for servers in my DMZ, I can granularly allow specific traffic, such as to/from the SMTP gateway/relay in the DMZ, to connect inbound from the DMZ to an internal (LOC) mail server, and know that it comes only from a non-routable private address. I get this warm feeling knowing that only a non-routable private address from the DMZ is allowed on those one or two inbound connections, as opposed to a public address deployed via Proxy ARP. Granted, anti-spoofing, etc., on the NET interface should help protect from attackers u...

Hello all, hope all is well this maybe outside of libvirt-users.... Can you nest macvtap devices to ultimately receive a real routable ip on the nested vm? I have a nested vm up and running. Both vm and nested vm are centos 7 on arch linux host. The first vm uses a macvtap in bridge mode receives dhcp from an external dhcp server. I start the second vm and dhclient hangs and never receives an offer. I stood up a static interface...

...authentication) because I think the root cause is something different. I think the problem is the following FROM line in my SIP INVITE transaction: From: "MYNAME" <sip:16667778888 at 172.31.253.4>;tag=773a3e6a-a677-4fb1-95fc-54b379b650a4 The IP address above is an internal/non-routable IP, so Twilio is rejecting it. For some reason Asterisk is not replacing the private IP with my public IP address. My pjsip.transport.conf contains a stanza for this transport with: local_net=172.31.0.0/16 Is that all that's needed for Asterisk to replace the from IP with the external IP?...

.... The problem I have now, is any client workstation running on network B, MSWindows 2K / XP / NT cannot connect to the primary domain controller which is in network C. The clients cannot even see the network domain in the explorere window. I believe the problem is related to NetBios, which is not routable, but I am not sure how to fix this issue which is a serious one, as no one can connect from the client to the main server. Any help is appreciated. Regards, This message was sent through MyMail http://www.mymail.com.au

...have a question. I have a routeable /24 netblock including a server at a colocation and I would like to use tincd to tunnel part of that netblock to an internal network on another location being connected to the internet via gateway with DSL link and a single static IP address, so I can use public routable IP addresses on the local network. I have tincd 1.0 pre7 installed on both the local gateway and the colocated server and communication between the two hosts works fine. I'm having troubles though routing packets. I am a bit dazzled about the arp and mac stuff in tinc-up. Should I be using a...

The usual way to do NAT: iptables -A POSTROUTING -t nat -s $INTERNAL_NET -j MASQUERADE iptables -A FORWARD -j ACCEPT Now, the problem I have is that my LAN is mixed NAT''d addresses and routable IPs. I have a host of FORWARD rules to determine which packets get sent onto which servers (routable IPs). My worry is that if I put in the "iptables -A FORWARD -j ACCEPT" it''ll defeat the whole purpose of those entries. My question is: How do I set up a FORWARD for JUST the...
