gnugk h323 proxy in checkpoint NG AI dmz

hi and sorry form my english.
i’m using the last version of gnugk 2.0.6

i test the proxy in lan and it work very well.

i put my proxy into a dmz and now i’m able to call from lan to and internet IP, but not viceversa.

when i call from outside to inside the connection die on the proxy.

i’ve some strange comportment on my firewall, udp connection are natted but is not the same for tcp connection, anyway it’s working for outgoing connection..

if you need other information such .ini configurations or firewall log i can send ti by email.

thank you to all !
