AnyConnect Mac client drops just after connecting

[yves_forget]

Hello everyone,

I'm on a Mac connecting to a Cisco ASA 5510 with AnyConnect VPN client.

The connection is established and it works for 15-30 seconds, then the connection drops.  AnyConnect will reconnect, and then it works fine.

I noticed in the logs that it reconnects with a smaller packet size.

Anyone experiencing the same problem ?

Any hints ?

Thanks,

Yves Forget

change MTU under your Group Policy

asa# conf ter

asa(config)# group-policy DefaultVPNPolicy attributes

asa(config-group-policy)# webvpn

asa(config-group-webvpn)# svc mtu 1200

or

Remote Access VPN->Network Client Access->Group Policies->your policy->Advanced->AnyConnect Client-> set MTU 1200

That solved my problem.  Thanks!

Problem disappeared when I upgraded from VPN Client version 2 to VPN Client version 3.
