we recently changed our internet connect from a 2meg line to a 16meg atm circuit. for some reason one of our site to site vpn's could not use the vpn, i do not know if all were like this though.

nothing had changed with regards to our ip addressing at all so i do not understand what could be the issue. i did not have time to troublshoot this on the pix before we had to fall back to our 2 meg line due to other reasons. we are switching across again on sunday and i'm wary that this will happen for all our vpn sites again. our isp says that it does not block any traffic passing through it so it could not be that. i was just wondering whether anyone had come across this or has any ideas? i will post the outcome after sunday.

thanks
