RV042 VPN bringing down my network?

    Hi all,

    I've had some strange issues occur over the past two days with our main RV042. It started off by not allowing me to access the web gui (or at least being extremely slow to open) yesterday. Today, we had some users in a remote office complain that they couldn't connect via the vpn. So, after checking on the main RV042, it appears to be dropping the connection and just behaving erradically.

    I've tried to decipher some of the log files to figure out what's going on, but they aren't much help (to me anyway).

    We recently installed a new Cisco RV042 in our branch office, which connects via vpn to our main office which runs an older Linksys (sans Cisco) RV042. I think this may be part of the problem, although it's been working without any problems for a few weeks now.

    Has anyone come across any compatibility issues between RV042 types (Cisco and Linksys) that would cause one to be brought to its knees?

    MTU Values can make a difference. the older Linksys models on certain firmwares require you to add the MTU value manually. Normally 1500 for Cable/Fibre connections and 1492 for ADSL. aslo make sure both models have the latest firmwares,.

    Thanks Simon. In the end, it turned out to be a defective RV042. We noticed that it was heating up way too often for too long, so in the end, it stopped letting us connect to it unless I unplugged it for awhile. I replaced it with a newer model, and the issue stopped. Thanks for your help.
