Can you loop back through the Astaro Firewall

kap1396
Can someone let me know if the following is possible.

I have 2 machines on the 192.168.254 subnet on the private side of the firewall. I have a public ip bound to the external interface of the firewall. I have MySQL server installed on one machine and I have MySQL client installed on the other. I want to be able to make a connection from the MySql client machine to the MySQL server via the external interface IP address. 

Here is how I tested. 
From MySQL client i tried the following command: 
telnet (external ip) 3306
I can not make a connection

Thanks

    This is not possible.  I can't give you a complete breakdown, but what I have seen in my trials is the SQL server tries to make a direct connection back to the client rather than through the firewall.  This appears to happen due to the double NAT that is taking place; outbound and then inbound.

    ttfn,

    put the server which should be reachable from inner- and outer net to another ip-range.

    for example: 
    server: 192.168.168.1
    internal clients: 192.168.167.0

    should work fine!
