hi everyone

I'd like to ask - how MTU affects link/connection of a 
tunnel if MTUs on both ends are different?

I'm asking because I'm seeing behaviour, symptoms which I 
think relate or are directly caused by:

_Aclient(auto=1500) <=> server(out iface auto=1500), server 
other iface

_Aclient vpns in fine, server's 
rightsourceip=, and server is 
pingable from _Aclient as any other node on 
is, but!
_Aclient cannot ssh to the server nor can to any other node 

Normally I'd blame, with high certainty, MTUs but because I 
only begin looking at Strongswan I'm looking for experts to 
share few thoughts and advices.

many thanks, L.
