I have some anyconnect phones (8945). I dont have a proper SSL VPN server (such as ASA or IOS router). I tried but have been unable to get my anyconnect laptop software connecting to an openvpn server I set up as a test. The issue seems to be openvpn wants certificates to be involved. In the case of cisco phone, the phone can send a Cisco cert or I can have the user prompted for username and password. I would want to try the 2nd option (not ideal but want to see if it works).

I thought I could use any SSL VPN server, but I think openvpn is out because of client cert has to be subordinate of server cert. Which isnt possible with cisco phone. When I try connecting with anyconnect software the software complains there's no cert. So seems though the server is always expecting cert.

Can anyone with more experience confirm this? And may be suggest some open source software to run a SSL VPN for authenticating client with username and pass?

In Adtran-speak, what do they mean when expediting COS 5? In Cisco-speak, they talk about voice traffic being DSCP 'EF' which is Expedited Forwarding', not sure if it's related.

Which STP type are you using?

There's a few things going on here and I think more info is needed to be able to make some proper suggestions to you :)

Ridiculous sloppy dev backdoors aside, it actually looks pretty slick from my POV.

Thanks. I'm working on a set of YouTube videos about network security stuff that people can do for free, which builds on what I said in that article.
