I am having trouble accessing the internet through a linksys RV042 from one subnet in a two subnet setup. Here is our setup:
T1 connection to the Rv042, Ethernet Address of RV042 --> 192.168.56.2 . There is another Adtran router provided by our ISP that has a MPLS VPN setup to a remote office, that routers IP address is 192.168.56.1 . On the other end of the VPN there is another Adtran with IP 192.168.2.1 .
From a host on the .56.0 subnet I can access the internet and I can also access hosts on the .2.0 subnet, however I cannot access the internet from the .2.0 subnet. I have programmed a static route in the RV042 that has 192.168.56.1 as the gateway to the .2.0 subnet, which appears to be working correctly, as hosts can communicate between the networks.
When trying to access the internet from the .2.0 subnet the last hop the trace route gets to is the 56.2 which is the Ethernet interface of the RV042, however I can ping all the way to the outside interface (public IP) of the RV042. MY ISP says this is a problem with the Linksys router, and Linksys says its problem with the ISP's setup. Any one have any ideas or suggestions? Is the linksys capable of being an internet gateway for two subnets? Does additional configuration need to made to the VPN routers supplied by our ISP?
