I just tried with changing the hostnames in my RouterConnections to IP
addresses instead, and removed both Passphrase and PublicKey, so no
authentication. What I get then is:

[astan@franz ~/silc-server-1.1.11/lib/silcske]$ sudo
/home/astan/silc/sbin/silcd -f /usr/local/etc/silc/silcd.conf -D 99
[Logging] [Info] SILC Server started
[Logging] [Info] Incoming connection h251n2fls33o879.telia.com (213.66.197.251)
[Logging] [Info] Connection h251n2fls33o879.telia.com (213.66.197.251)
is backup router
[Logging] [Info] Invalid server ID sent by 213.66.197.251
(h251n2fls33o879.telia.com)
[Logging] [Info] Closing connection h251n2fls33o879.telia.com:28876 [Server]

I don't see why I should have to use IP addresses just because the
reverse lookup does not match the FQDN in the config, but I can live
with having to specify IP addresses. However what's the problem above
about? Invalid server ID.
