Firewall/NAT

I have a current working network consisting of

Office 1 : 1 adtran router 192.1.10.150 connected point to point t1 to office 2.
office 1 has a dsl router/modem (bell south) 192.1.10.160.
office 2 internet access is provided via the ptp t1 link to office 1.
office 2 is 192.1.11.0/24 with the default gateway set to the local adtran 192.1.11.150

I want to replace the dsl router/modem at office one with a monowall with highspeed cable.

I replaced the current dsl router with monowall using same lan ip.  this should work as the old bellsouth netopia did and since the ip address is the same any routing rules in the adtrans should work.

problem: local traffic @ office 1 works great. internet traffic at office 2 now no longer works.

I could not ping the monowall from office 2 untill I added a static route on the lan interface to reach 192.1.11.0/24 via 192.1.10.150. at this point I can ping the monowall and resolve dns. still no traffic and no site found in browsers. The logs on firewall show blocking traffic on the workstation ip address. what could be stopping the browser from working?


Thanks

the log show the firewall blocking requests from the office 2 network to go to the sites

The adtran is not performing NAT so the Monowall is seeing internet requests from office 2 as 192.1.11.0/24 subnet.  You will have to add a rule on the LAN interface to allow traffic from that subnet to any.
