TCP retransmission

[nchrissos]

Hello guys,

I 've been testing pfsense and I have a problem with tcp retransmissions. My set up is server ---> pfsense ---> router. Pfsense nats the server, and pfsense port forwards to a different port on server (windows firewall permits the port).

Searching through the internet I found an old bug for virtual pfsense that says to disable hardware checksum offloading, and I did so. Unfortunately this did not solved the problem.

Do you have any idea what could be the problem?

Thank you
