Hi all. I'm new in this list so I don't know how it really works. Anyway... I am having a problem trying to connect two EPs using GNUGK as a proxy and gatekeeper and maybe someone could help me. Th GNUGK has a public IP and both of the EPs have private IP but only one is behind NAT for the gatekeeper point of view. The other one ( the NATTED one ) is behind a linux NAT ( iptables ) where everything is forwarded to the private ip of this computer. When I try to connect from the first one ( the non nated ) to the second one, it always close the connection before getting established. The same scenario but without the NAT works perfect. I have made several traces in the nated client side and the difference between the two scenarios ( with nat or without nat ) comes after sending the Connect Q931 packet when I get this error: H225 Accept for H245 failed: Interrupted function call Does anyone know why it happens ? If anyone thinks that know why happens but need some more traces or something like that, please let me know cause I have a lot of traces done. Thanks in advance.
