I'm hoping someone here can help me figure what might be happening here. Source folks initiate a telnet session and they're saying they see the packets go out on their FW, but unable to make a connection. On my FW, I do a "sho conn", and I see the connection but it shows a "UB" flag.
The command reference guide shows:
U : Up B : initial SYN from outside
Could someone help me determine what this might mean?
