Up to this point, one of my customers was working fine.
Now, I am configuring an online backup that initiates communication to their backup servers. I use the same vendor at home on the same firewall (other than the rules), so I know it works.
Masquerading works, etc.
I set up Service definition for TCP on their 3 ports (6701:6703). I've also defined their backup server as a defined DNS host and nslookup works and resolves fine.
I've setup Packet Filtering outbound and inbound for those ports (do I need inbound?). I've also turned them on.
However, it fails to log in to their server. In the packet filter, I can see the outbound connection, but not the return.
I've even made the rules number 1 and 2 just to be sure.
I then tried a telnet connection on that port to their site and I don't get any sort of logon/herald (not sure if I should). I do need to test that once I get offsite.
I know I am missing something pretty obvious, but I am approaching brain fried mode. [:S] I have confirmed with them that they are only using TCP (to the best of their knowledge).
I'm going to wireshark a connection on the firewall to see what I can see as well.
thanks in advance for any advice.
Mike
