Steve - You said you have an FVS338, right? Which timeout values on which setup screen did you change? I want to check my FVS338 to see how it's set. BTW, you did define (under Security >> Services) a service for UDP 700, right? And then under Security >> Firewall, you added incoming and outgoing rules for that service ?

I have increased the timeout values on the router that is attached to SG1::. Hopefully this improves matters. -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of hvlems at zonnet.nl Sent: Sunday, June 10, 2012 03:08 To: hecnet at Update.UU.SE Subject: Re: [HECnet] netowrk flapping.... Bob, on A44RTR is see SG1 flapping as well. After breakfast I'll see whether there is a pattern. Initially I thought it was the linux laptop going to sleep after a whule. That may not be the case.

Verzonden: 10 juni 2012 01:32 Yup, that's basically a deficiency I've got... Yeah, but the next question is "Are you the only one", or do other people's routers have similar timeout issues? Bob
