-internal network: 192.168.50.x
-private network between my astaro/isdn router: 172.16.0.x
-ip public: 202.22.221.x

my router:
ip adress: 172.16.0.1

i've 3 network cards in my astaro:
eth0->192.168.50.x
eth1/eth2->bridging with standard interface=202.22.221.x and additional adress=172.16.0.x gw:172.16.0.1

i create a vpn between my astaro with another astaro

I don't quite understand what the 3rd NIC is doing. explain more?

Does the other end also run an ISDN with a private LAN between it and the firewall? If it doesn't, if it has a public IP at the firewall, then make it the endpoint for the ISDN side to call. The other end with public IPs would use as an endpoint so that it waits for a connection since it can't call the ISDN.

If both ends use a private IP lan then you will have trouble unless the ISDN router does DMZ and passes all traffic as if the firewall had the pub IP.
