Hi,
Have opened a ticket with support, but will post here on the off chance somebody can solve this here first.

Had a S2S vpn configured on a 2862 and was natting all traffic to a single IP (1.2.3.4 in this case sanitized) set under My WAN IP

This setting is missing on the 2962

How do i configure the 2962 to do the same as my settings in the 2862?

If i choose NAT mode on the 2962 then the tunnel doesnt come up at all, regardless of what i put in Local and Remote Networks.
If i choose routing mode and then tick Translate whole subnet and choose the LAN and pop in the details then the tunnel comes up but it doesnt NAT from a specific IP as it just keeps defaulting the Local Network to 1.2.3.0/32 rather than 1.2.3.4/32 and none of the traffic goes over the S2S as they only accept traffic from the natted IP.

Whats the equivialnt settings for the 2963 to match that of the working 2862 config?

Thanks in advance
