HTTP session problems since setting up VPN

Post by Jools » Sun Oct 10, 2010 9:20 pm

Hi All,

I have an open vpn setup comprised of three offices. The head office has two tunnels, one to each sub office and the three are bridged into one large subnet. Overall, the whole setup works perfectly with all three servers (one on each site) visible across the entire network but there is a problem with a web app at one site.

Since setting up the VPN, the web app seems to kick users out so they need to log in again. This can happen 30-50 times a day seemingly at random. Before I start dissecting everything, has anyone come across this before?

Thanks.

how many machines in each office, and how many users on the vpn?
my first thought is that you have a broadcast storm created because you are using a bridge
if you dont need a specific layer2 protocol, you will gain performance and quite possibly fix your problem by changing to a routed setup.
here is how to link 3 lans with a routed setup:
