[Swan] NATD IP different than configured IP

[Craig Marker]

It looks like 1.2.3.5 is the IP address of the nexthop router on the way to 6.7.8.9.

So it goes 1.2.3.4 —> 1.2.3.5 —> … —> 6.7.8.9. Does that help explain anything? Is there some configuration value I have that would allow for this? I’ll double check to make sure I didn’t make a mistake anonymizing this.

Is this the ipsec status output you’re looking for? This is from the client machine.

yeah. assuming you didn't make a mistake anonymising this, it could
never use 1.2.3.5 as its local IP. So I have no idea what's happening
in your case.
