Hi I have a atrange problem and don''t know where to look anymore. I have 4 interfaces running on RHE3 on a Dell XEON server 2.8Ghz 1Gb RAM. The primary use (only one at this stage) is for the server to handle mac address authentication of clients which it does. The problem however has to do with througput. I have 3 DMZ''s which one is a private range doing masquarading and

On the firewall, what is the rationale for giving eth1 an IP address that is also assigned eto eth0? (Rather than a private one.) -- Taso Hatzi caesar 17 <<-salad cjbx jc vdwwjar jc xi jc jd salad

Good point Stijn, I am sorry to post without subject and such it must be the early morning. The relevant entries in my rules file: ACCEPT net fw tcp 25 ACCEPT net fw tcp 80 ACCEPT net fw tcp 22 ACCEPT net fw tcp 21 ACCEPT net fw udp 21 REJECT loc

hello there, im running a 3interface inet, dmz, loc. i have some public ip addresses. one public address is the router of the provider, the second one is the linux box running shorewall. all other public interfaces are on the dmz nic with proxy-arp. now whenever i do a traceroute (the dmz boxes are windows, icmp traceroute) the very first hop gets timeout/stars, then the router of the provider

Hi! I was thinking, is there a way to use a linux box with Samba running in the DMZ of a firewall and to validate logons from the internal network? I.e. the users workstations are on the protected net on 192.168.111.xx and the Samba PDC resides in the DMZ, running subnet 192.168.222.xx. If it's possible, what ports need to be open?

I've got my asterisk server in the DMZ of my local LAN - I've used my Budgetone and GXP2000's from the Internet- on direct IP connections with no problems. However, I'm about to deploy about 5 phones (either budgetone or GXP2000's) all on a LAN behind a NAT- on a different network than the Asterisk server. Should I look into using STUN servers? Will this setup be a

Hello, I''ve shorewall running a three interfaces firewall (net, loc, dmz) and I''ve got performances problems. My measured bandwidth from internet is up to 6.8 Mb/s, and I "only" get 3.5Mb/s on my LAN and 5Mb/s on my dmz. I checked with iperf, and all my interfaces (eth0, eth1, eth2) can actually work at 10 Mb/s. I tried disabling all the rules from loc to net

Hi Everyone, Is it possible to have a SIP Phone work remotely if it's behind a Router performing NAT without connecting the Router to a VPN? The Asterisk Box will be in the DMZ.

I'm trying to set up * server behind NAT. The box is set up as DMZ in my DSL router, i.e. all incoming connections without explicit port mapping are forwarded to *. So far I'm unable to get this setup to work for either IAX or SIP (tried IAXComm & XLite softphones on public IP address). Data seems to come in fine (IAX/SIP debug shows message interaction taking place), but there is no

Hi, I'm trying to configure Sipura 2000 (behind NAT) which connects to Asterisk (public IP, no NAT) and having interesting results. When Sipura is behind Linux/NAT firewall it works great and no special NAT settings on Sipura are necessary. The issue I'm having is when Sipura is behind Linksys broadband NAT router. Sipura gets registered with Asterisk just fine, but I can't hear

I ditched the idea of using Asterisk straight through my router, there was too much to set up in too little time for me. I've found a spare machine and installed Asterisk@Home on it. Things run smoothly except for connecting to my IAX provider; It doesn't even look like packets are going out at all. Here's my config: ANY Cable ------> Firewall/Router

I have a user that just got a broadband connection so she could have an extension off our pbx. The service is DSL and uses a speedstream 5200 dsl router. I sent her a Polycom IP300. At first it would not access the config files via ftp so I had tech support walk her through setting the phone's internal IP to be the dmz. This allowed me to set up the phone using the web interface and now

I am considering replacing my old checkpoint and watchguard firewalls witha single Linux box using iptables and shorewall. I have two ISP''s (with separate routing tables), two DMZ''s, at least one VPN to a remote office, and a local trusted network. The configuration will look like: +----------------+ | | net0 ----------+ eth1

Hi everyone, I have this problem that I'm not sure what's the best solution for it. I need your input & help... I have an internal network behind a hardware firewall. All traffics go thru. the firewall. One of the firewall's rules is that it doesn't allow internal network accesses internal resources that travels outside then come back. In the other words, it drops all

Hi I have samba installed & running successfully on a Solaris 8 server. directory shares were working as expected until the machine was put on a DMZ, and now it's stopped working. I can ping from my PC to the server, and telnet, but samba seems to have no route through the firewall - possibly the firewall needs to have different ports opened up to allow samba traffic through? I need to

I have used rsync on many systems, and never had a problem. I am stumped on what to do with this. I have a box behind a LinkSys router and I can not "push" or "pull" data to or from it from anywhere. When I try, it logs into the remote server, gets the file list and just stops. The remote server shows a process running until I control-c out of it.when I do that, I get: rsync

I''ve configured our DMZ apache webserver to proxy connections from our roaming users into our internal puppet master running under passenger/apache. Everything is pretty much working but because I am using SSL between the proxy server and the puppet master, the master treats the connection as authenticated as the proxy. My current work around is to allow access to all catalog and
