The log messages gives me the following back Jul 11 18:17:35 ipfire Testn2n[13565]: UDPv4 link remote: 192.168.20.2:5329 Jul 11 18:19:09 ipfire Testn2n[13808]: TLS Error: client->client or server->s= erver connection attempted from 192.168.20.2:5329 Jul 11 18:18:01 ipfire Testn2n[13565]: event_wait : Interrupted system call (= code=3D4) have never seen this message (in the middle) before... So i looked to the configuration file on the TLS-client where the "Remote Hos= t/IP" was stated with the 192.168.20.2 (red0 IP), i changed it then to the re= mote IP (in versions before Core 70 this was not necessary) and the following= log output was stated. Jul 11 20:22:49 ipfire Testn2n[6875]: Expected Remote Options hash (VER=3DV4)= : '9e986809' Jul 11 20:22:49 ipfire-bbach Testn2n[[6875]: UDPv4 link remote: 172.11.xx.xx:= 5329 Jul 11 20:23:50 ipfire Testn2n[[6875]: [UNDEF] Inactivity timeout (--ping-res= tart), restarting Looks like a closed firewall. Portforwarding from both upstream routers to IP= Fire was made, outgoing FW was in mode 0 . May some one have an idea what=C2=B4s causing this problem ? Greetings=20 Erik --===============5514455231340939305==--
