We have almost identical networks in two offices, with the only difference being, one uses an RV042 and the other an RV082.The setup is: two WAG54GS ADSL modems carry PPOA ADSL connections with static IPs to the two WAN ports of the RV0XX.The WAG54GS routers are configured to DMZ all incoming traffic to the relevant WAN IP of the RV0XXs. VPN pass-through is also set on them. The RV0XX port forwarding is set to forward a selection of traffic such as, PPTP, HTTP, HTTPS, RDP, POP3, SMTP and Remote Desk to the external adapter of an SBS 2003 server which processes all operations including ISA and Exchange.Mail for Exchange arrive through both ADSL connections for redundancy. VPN connection requests from remote users to the SBS come in through both ADSL connections.The office fitted with RV042 works fine and does all the following without problems.The office fitted with RV082 has issues. Remote VPN requests comming from ADSL to WAN port 1 of the RV082 connect successfully to the SBS2003 server, but the VPN requests coming from ADSL to WAN port 2 fail to connect! Similarly, incoming mail destined for Exchange don't get through if coming from ADSL of WAN port 2.I have updated the firmware on both RV042 and RV082, but the RV082 still has the above issues.
