Hi Everyone,
I've been given a curious problem to solve and I'm completely stuck..
We have 2 sets of firewalls, set up as pairs to load balance incoming Anyconnect VPNs.
On the primary Firewall in each pair the clients connect ok and send/receive traffic successfully. If i join the second firewalls to the VPN Load Balancing Cluster the clients connect to these devices ok, but we only get Rx traffic, and no Tx traffic. (As seen on the ASA VPN Monitoring)
We are using FQDN for the redirect and we are using Certificates to secure the IKEV2.
We are using the current Anyconnect client and ASA version 9.8
Has anyone seen this before, can you give me any pointers where to look?
Thanks for your help.
RC
