Route traffic from far far side
I'm looking for instructions or routing from a 'far-far' side. Right now I have a VPN between my network and their network. At their site a T1 links to their branch office (calling this far-far). I'm trying to get traffic from 192.168.22.x to 10.0.55.x
my site = siteA, has a Cisco RV042 VPN router 10.0.55.0/24
far site= siteB, has a pfSense 2.01 router connected through VPN to siteA 192.168.33.1
siteB also has a Cisco 1760 router w/T1 interface (192.168.44.1) that talks to siteC eth0=192.168.33.2 and T1 eth1= 192.168.44.1
far-far site= siteC, is a remote branch site, all traffic goes out through a Cisco 1760 to siteb eth0=192.168.22.2 and T1 eth1= 192.168.44.2
The traffic to and from siteC and siteB works fine.
The VPN traffic to and from siteA and siteB works fine.
Is this a NAT issue?
Do I need a firewall rule at the pfSense router that allows the 192.168.22.x to 10.0.75.x? I have one for the 192.168.33.x to 10.0.55.x
You probably need to add routes at sites A and C so that they know how to get to each other: via site B.
Unless your are pushing routing information or running some routing protocol it's probably easiest to just add them as static routes.
