i configured a site to site vpn on cisco 1811. i can ping remote network and access its resources.
site A =1811
site B = netscreen
I am facing problem when i access any website at remote.
i can login to website and browse it. but when i submit any form on remote webserver site. i am getting time out
after 2-4 minutes.
Before establishing VPN it was working fine.
then i disabled vpn and it is working.
can any one knows about this problem.
You could attempt to calculate the amount of extra header which is added by VPN. But this will vary depending on the set of options that you choose in VPN. I have found the information to do this calculation difficult to find with precision. I just started experimenting to find a value where things got better and experimented up and down from this value to find the optimum value. For us it works out to be 1375. I suggest that you start with that and try values larger and smaller to find what works best for you.
