I have a 501 that was up and running for a long time we changed ISP setup now have a DSL (netopia router) I changed the ip's of the 501 to the new range (501 and outside route) it worked for a few weeks then stopped.
We have a 2950 where each isp goes first then to each pix. 1700 for the t-1 to the 515 and netopia for the 501.
I am a newb so I had an outside firm do the config a few years back orginally and when we changed our phone service I lost my adtran giving me internet to the 501 so we got a dsl line I figured how hard would it be to just swap the ip's. Well like I said it had worked then stopped.
I can ping from the 501 to outside www and into my network but when I use an outside xp to vpn it never connects. The vpn is a 2000 server I can connect from inside the network to the vpn so that makes be believe the vpn server works.
We also had a new voip phone system installed and our 515 was the default gateway and it had to be changed to a 3560 could this be the root. The 501 did work for a few weeks after this change so it makes no sense to me.
Ok, so if I wanted to start from scratch and reconfigure my 501 I am lost as to what procedure to follow. Can someone point me to the correct document for my setup?
