Hi,
The AnyConnect (and IPSEC VPN Client) interface is a virtual interface, no packets ever make it to the gateway mentioned in the
defautl gateway route. The traffic is just encrypted and sent to the remote VPN endpoint, it is up to the VPN server to decide how
to forward this traffic.So it doesn't matter what the gateway is , as long as it is in the same subnet as the interface.
This behavior applies to Local IP Pools as well ascertaining an IP from DHCP. The DHCP Server does not even need to have the
router (default gateway) option configured, since it does not apply to the VPN virtual adapter.
With Anyconnect, the gateway points to the 1st IP in the assigned subnet (Or the 2nd ip , if the assigned address is the 1st ip )
Regards,
Rick.
