VPN passthrough on RVS4000 not reliable

    Hi gang:
    I "upgraded" from a d-link di-604 to an RVS4000 so I could VPN from work to home. However, in doing so, I have compromised the reliability of the home to work VPN solution. I am using my work's VPN solution (pass-through on the RVS4000) pretty regularly. Where it used to be rock solid on the D-Link (connects immediately every time), the connections with the Linksys are very poor. By that I mean sometimes I have to try 4 or 5 times before I get a connection. The failure mode is a long wait with the client trying to connect and then a message from the VPN client that says "Connection to server lost... try again." My work has several VPN gateways all over the US and all behave the same.

    I called Linksys tech support and they had me switch the MTU size from Auto to manual 1400. He said that if that did not work, try 1300 and then 1200. And, if that does not work, then try upgrading the firmware. He said that he was sure that one of those would fix the problem. Well, you know what. None of those things helped.

    Does anyone have any experience with that sort of problem?

    Damn. Two years, almost, and no replies. I have the same issue with RVS4000, it makes my passed-through VPN connection from my work laptop drop packets or something like that. My clients running through the VPN connection repeatedly lose connectivity (for instance, outlook loses its connection, pidgin loses its connection, my SQL tool becomes spuriously disconnected from the database, etc.)

    Has anybody gotten this to work reliably? I disconnected the DSL modem/RVS4000 combination and reverted back to my Westel DSL/Router box, and the VPN is rock solid.
