Hello all, I have a server on my private network that is configured as an NIS server and mapped to a "public" IP address on a firewall. All other TCP ports (SSH, iperf, you name it) are visible from the outside - but the portmapper-managed ports (port 111 itself and the YPSERV/YPXFRD ports, etc.) are not visible from the outside - even though they are alive and well on the internal network. So, here's the question: is there anything special as far as portmapper's networking/security setup that is at play here? Thanks. Boris.
