Cannot Access VPN after IP Address Change

[Guest]

I have been struggling with this for a bit now and I cannot figure it out.
Last week I changed from DSL to T1. I went from using a modem/router to
using just a router. This also included an IP Address change. VPN did not
work immediately after the switch. I found a reference to the old IP address
in the routing policy, so I changed that. This did not, however, solve the
problem. I removed all restrictions including placing the server in a DMZ to
no avail. I have had a long tech call with the router people and they have
indicated that it is the server. The only thing that I have noticed that may
shed light on the subject is the iaslog file entry for starting RAS. It
looks as though there is a login entry before the change and now there is a
blank where the login would occur. Here are the log file entries:

Note that after the IP address in the first two entries there is an entry
"administrator". That no longer appears.

I am running out of ideas with the issue. Any help would be greatly
appreciated.

Assuming you use PPTP VPN, what's the error code? or any errors in the event Viewer?

The error code is 628.

In this case, I would check the new router or firmware first.

It did turn out to be the router. I switched it out with another and there
was no problem. I had talked to the router company, but there must have been
some part of the configuration that was not right. Thanks!
