Has anyone had a problem similar to this?? BEFW11S4 router forwards several ports to internal servers on the private network. All of them but port 80 work fine in serving outside clients. As for port 80, incoming packets get forwarded correctly, we can sniff them arriving at the target internal server. The server responds OK but the expected follow-on response to that from the client never comes back. (It tech terms of the TCP 3-way opening handshake, we get his SYN and send a SYN-ACK but we never get his ACK, he keeps repeating SYN to re-try opening the conversation). The reason we don't hear from him is, we think, that he doesn't hear/get what we send to him. And the hypothesis is, the router is failing to properly NAT our packets and they never get out of the building. Any experience like this out there???
