[Connection established successfully but no traffic] Openswan U2.6.42/K3.4-3 < Site to Site > strongSwan U5.3.3/K3.18.23 #226

Open Bubelbub opened 7 years ago

Bubelbub commented 7 years ago

Hey guys,

I extended my tests from small internal test system with same environments to a real environment with real machines. On the one site I have a OpenWRT router with UMTS Dongle (strongSwan U5.3.3/K3.18.23) and on the other site a IPCop router (Openswan U2.6.42/K3.4-3).

The local test works after @letoams helped me. Thanks again. https://github.com/xelerance/Openswan/issues/225

And now the basic connection work but the difference between Openswan and strongSwan seems a bit big.

I copied the configuration from server to client and changed right and left. Then on start I got a few "deprecated" warnings which I removed from the client configuration.

Is this maybe a problem because I can't forward ports on the UMTS dongle site? The server have opened IPSec ports - but the LTE Stick / UMTS Dongle is not able to have opened ports. But why the client says he is connected and the server said the client isn't connected?

Tried with Fritz!Box 7430, too and same result. 👎
