Consider that you have to state the remote domain if you client uses another search domain, what I assume.

So if you want to request the remote host name is "host" and its domain is "local" you need to type "host.local" to access it.

Ok. Yes, no way to do that as far as I know.

@CodeNinja said in How to setup a second local network for an IPSec connection?:

I'm also curious if its preferred/best practice to use "supernet" or this "multiple tunnel" construction like i currently do.

In many bigger scenarios, I see "supernets" or bigger CIDR masks to simplify tunnel deployments. Especially in centralized structures with one or two "main" sites with big uplinks and many small/branch offices network design often tends to do sth. along these lines:

Roll out big network structure on main(1) -> e.g. multiple 172.19.x.0/24 networks for security segmentation Dial Up / RAS VPN uses IP ranges either from an upper 172.19.x segment or another IP range altogether (e.g. 192.168.vvv.0/24) Branch offices use separate range -> e.g. 10.10.bbb.0/24 for office 1, 10.20.bbb.0/24 for office 2 (or 10.11.bbb.0 if you have a whole lot of branch offices).

With that setup, you can easily do tunnels from "main" to "site a" with <172.19.0.0/16> <-> <10.10.0.0/16> and have no problem whatsoever to grow in either space. If you have the need for new networks on site or on in the main location - just add another VLAN with /24 and as your tunnel is set up with /16 it already includes the new networks.

So yeah, pretty common to use CIDR ranges bigger than your local network to add some "space to grow" lateron.

I also noticed this morning that one of the connection had 8 tunnels where i expected only 4. 5 are duplicates from eachother and 1 is missing..

That seems strange. A duplicate can (and will) happen at times, when rekeying gets near and the lifetime is about to expire. Then it's pretty normal to sometimes see every phase with a second entry as the old one gets "disabled" (but not disconnected) and the new one takes over so the rekey/lifetime turnaround goes smooth. You then see new traffic accumulate on the newer P2 and the old one won't get any more and after expiry should vanish a few seconds/minutes later. But having the same phase 5 times is strange. And some were brought up only seconds after another. Weird. I'd disconnect the whole bunch and reestablish the tunnel and check if that happens again. Perhaps something with the edgerouter on the other site? Maybe setting the split option in P1 of the connection could help if pfsense tries to group the connection but the edgerouter doesn't support it (fully) - but that's just a guess.

Very strange the tunnel is now up and it seems to be working.
Niw the problem is, that if we ping the other site no response from the host is coming. But on a tcpdum we see, that the ICMP reuqest was received and the echo is send.
