I set up an ipsec site-to-site vpn with rsa authentication: One site is an astaro 7.404, the other 7.403.
Following problem: The tunnel works but after some time it only seems to be working, because it is just possible to inititiate a connection from one site to the other - and it is allways the same site; after having done this it works fine for a while and then the same thing happens.
I tested different authentications, different gw-type (initiate on both sites or initiate nd just answering) - can't find any solution.
Thank you for your help!
