Re: [NV] Cisco DPq3212 and VPN slowdowns

What OS were they running before the downgrade to widnows 7? Why do you blame the modem first if the OS changed?

Sounds like too low of an MTU on the tunnel interface. What is the MTU set to?

It's two different PCs deployed from a corporate environment. The old PC was Windows XP with the Cisco VPN client that came before AnyConnect - no issues whatsoever. The new Windows 7 machine with AnyConnect - has the problem. I lean toward the modem or something like that only because the user lives in a place and uses an ISP and equipment different from everyone else I support. I doubt our IT that deployed the laptops was able to test with it.

I will check his MTU setting.

MTU for the VPN connection is 1406 from what I can tell.

A few quick searches on google of cisco anyconnect + windows 7 finds quite a few people with a similar problem. Since the modem is just a simple bridge it doesn't mangle the packets, it doesn't care what traffic you're sending.
