Cisco Anyconnect keeps reconnecting / VMWare bridged network / Windows 10

  • 772

I am running a Windows 10 VM in VMWare Workstation 15.5.1 build-15018445. From within the VM I connect via Cisco Anyconnect to a VPN.

Connecting the VPN with a Network Adapter as

  • Bridged (Automatic) results in reconnects every minute
  • NAT results in a stable connection

Now the funny part. If I initially connect to the VPN in NAT mode, then switch in VMWare to Bridged mode and let Cisco Anyconnect do a reconnect, the connection is stable as well with the Bridged mode.

Due to that the host needs to be connected to a different VPN, I need the VM to have configured in Bridged mode and using the work-around with NAT-first is getting tired and is sometimes forcing me to disconnect the VPN on the host first which leads to futher problems.

So I am hoping someone else has experienced such issues before and does have a hint for me or a configuration advise for the VPN admins.

  1. Change UDP timeout from 30s to 60s under VMwareNetwork Config. that solved for me. Connection stable for up 40 min
