hi,

i have a separate router on my green network which connects to our second location.

network_behind_router --------- router -------------- green_iface_of_efw
10.0.1.0/24                      10.0.1.5 || 10.0.0.8          10.0.0.1

i configured a route

   source          destination      gateway      
10.0.0.0/24    10.0.1.0/24    10.0.0.8


so far no problem... pinging vice versa works

but when i try to manage my server in the second network via rdp or vnc,
i can do that for 2minutes and the connections fails

i realized some entry in the firewall log like :

Mar 4 08:22:18      NEW not SYN?     br0     TCP     10.0.0.192   1519    00:60:e0:e1:e6:4c    10.0.1.11   3389


after that i tried to make a rule that allows all traffic from 10.0.0.0/24 to 10.0.1.0/24, but that doesnt change anything.

any idea???

I had a similar problem when trying to use a remote control program on a computer outside our network.  What I did was put my machine (either MAC or IP) in the "Bypass" section of the Proxy > HTTP > Configuration > Allowed Subnets Per Zone  and that resolved my issue.

It sounds like you have your default gateway set to the endian box, then endian is routing packets to your router.

Your PC -> FW -> Router -> Server B

Remember endian is a firewall, it looks at all the packets, and most likely its getting picked up by a linux firewall rule and droped as abuse.

A better setup would be to setup your router(10.0.0.Cool as your pc's default gateway, and the default route of the router, the firewall.

Clients -> Router -> FW
