They are Unix, and the people who set them up did not create a /etc/hosts file. Of course we already checked all the basics like logs, tcpdump and what not, but we could not find anything. That way you don't potentially break anything else while you test. A reverse lookup is just a normal DNS request to the FW so check the basics, are the packets allowed by policy? What do the logs tell you on the DNS server (are the requests even getting there)? Is there something different about how the OS on the SSH servers creates the DNS requests (size etc.)? Once you're 100% sure it's not something simpler then try the message size adjustments already suggested, but again before completely disabling a core ALG like this I would create a custom application set to ignore ALG and permit it for select problemetic connections. For example why would DNS inspection prevent a reverse-lookup? It shouldn't at all since essentially it's there for message-length checking/enforcement, DNS doctoring and only allowing the first DNS reply through. I think a key point that has been made already is you need to understand what the ALGs are actually doing per-protocol/application before playing with them. That way you don't potentially break anything else while you wrote: Netcomm also provide a useful router emulator for all their routers.I think a key point that has been made already is you need to understand what the ALGs are actually doing per-protocol/application before playing with them.
