Sudden problem connecting to VPN

I have OSX 10.6.8

I have been using Cisco VPN client 4.9.01.0280

For the last two weeks I have been using the VPN client with no problems. Suddenly it just won't connect. Is says it is contacting the security gateway and then never does.

Of course the company IT guys don't know anything about Macs so all they can do is confirm that everything is fine on their end.

Anyone have any thoughts?

Yes I have turned the computer off and then on again.

thanks!

Have you tried connecting from other locations? If it never contacts the security gateway then it may be a DNS problem. If you can connect to the VPN from other hot spots then it may be local to you.

What error message does it give? Time out? Rejections?

Depending on how your VPN is setup - is your certificate still valid? My company has renewals every year.

Last VPN problem I had, MMS wasn't enabled and the MTU size ended up being too large. I bumped it down from 1448 to 1380 and it worked fine. Just a thought.

OK, I found a restaurant with public wi-fi and I was able to connect to the VPN (I am in a strange, 2nd world country at the moment).

Get this though.. now it won't then connect to the remote desktop connection.

thoughts?

Once you are on the VPN you should be able to use ping to see internal machines (Assuming that the internal machines are setup to reply) FIrst things first is to see if you can get to ANY internal assets like an internal web page, or a share drive. If you can't get to anything internal you still might be having a DNS problem - except with your internal DNS.
