I am acessing a secure VPN client 4.0 service, which works correctly, performance is good, tracecrt to a sample site resolves correctly, and has good return times. I am using a link sys dsl connection to at&t, windows 2000 Sp4.
When the secure client software isnt running, the internet connection is slow, and seems to drop packets. Ipconfig all seems ok, default gateway is the 192.168.1.1 of the linksys, every tracert starts with the first hop failing, almost as if it is trying some route, then going down some obscure path.
The other PC on the home lan (doesnt run the secure client) and is fine.
Re: Very Slow internet access, when VPN client is off
Normally, the performance goes down slightly after encryption is enabled due to the extra overhead. The only possibility that I can think of is that your gateway router is using two different connections, one for IPSec traffic and another slower link for non-ipsec traffic. Guess you should check this with the administrator.
