There are some normal LAN clients behind the Linux firewall's GREEN interface, which can all access each other's shared services and also

i'm having a problem viewing logs on forwarded ports from the firewall to another server, i forwarded mail(port 25) from the firewall to an internal server. The problem is when i try to view the logs it just shows the firewall ip as the sender and not the original sender. -- Regards, Mark Quitoriano, CCNA http://www.atamanetworks.com

Hi, Following the directions for setting up bridged networking in the red hat virtualization guide and libvirt wiki, I set the following kernel parameters to 0 on a RHEL 5.5 server. net.bridge.bridge-nf-call-ip6tables net.bridge.bridge-nf-call-iptables net.bridge.bridge-nf-call-arptables Unfortunately, doing this broke the port forwarding I'd set up for VMs on my NAT networks, e.g.

Hello, I have a webcam that I wish to view from the internet. It is a wireless linksys model with an ip address of 192.168.1.15. I have it set on port 8081, 192.168.1.15:8081. I am using the IP Masquerade HowTo script. Here's the rule I added to my firewall script: EXTIF="ppp0" INTIF="eth1" EXTIP="`$IFCONFIG $EXTIF | grep inet | cut -d : -f 2 | cut -d \ -f

Hi listmates, Happy Thanksgiving! Does anybody know if there is a convenient utility to configure iptables on a CentOS 5.4 or 5.3 machine to do port forwarding? And if not, where and how does one put the requisite commands? Thanks. Boris.

I have a system with 2 interfaces, BoxA: eth0? 172.26.50.102 eth1? 192.101.77.62 My goal is to have a tcp port built on BoxA such that hosts on the 192.101.77.0/24 network can reach a port on a different box on the 172.26.0.0/16 network.

Perhaps someone with a sharper brain than I can solve this little mystery. I've Googled until I'm blue in the face, read all TFM's I can find, and tried several iptables rule combinations but just can't get the following to work. Here's my challenge: I have a CentOS-5.3 "main" server with a static public IP address running Apache, OpenVPN, and a bunch of other

Easy question here: I have a test network that looks like this (apologies for my lack of ascii skills): [hostc]---------------[Firewall]192.168.42.1 (EXTIF: eth0) /10.0.0.1 (INTIF: eth1) 192.168.42.10 (wan) |(lan) | +-------------[hosta] 10.0.0.10 (port 4242) | +-------------[hostb]

Hi all Is it possible to just forward port to local computer but not give open access for that port? If I''ve understood right that this rule does give ACCESS from net to loc too: DNAT net loc:192.168.1.5 udp 7777 What I''m trying to say is that it would work so that everything that''s coming from net to that local computers port is DROPed or REJECTed if it''s

Has anyone heavily exercised the TCP connection forwarding features in openssh? I use this feature quite extensively for secure web surfing. I run a ssh command like this: ssh -c blowfish -L3128:127.0.0.1:3128 squidmachine Then I set up Netscape on my local machine to use 127.0.0.1:3128 as a proxy server. Needless to say, this exercises the TCP connection forwarding feature quite heavily. This

Sounds like if you are testing this in the same place where the server is that your router may not be doing ?loopback?.. ask a friend to test it from their end, or at least reboot the router (some are fussy things) You can also test your ports externally from here: port tests regards From: Jesse McMillan Sent: Wednesday, March 30, 2016 8:17 PM To: icecast at xiph.org Subject: [Icecast] Help

What is the best solution? I dont want to have modify firewall's at all or do port fowarding. Ideally I would like a solution that with either a softphone or wireless hardphone one could connect via friends, family, or hotspots without reconfiguring their devices. What are people using? STUN?
