NAT - newbie question

  • There are some prodocols that embed IP address(es) in the data portion of a packet, like ftp. Does pfSense look into packet data and apply NAT on those addresses as well? What other protocols embed IP address or port information in their data?

    Is there any docs that I read to understand all this better?

  • There is an ftp-helper build in that you can enable/disable per interface for these kind if situations. Besides that no other protocol is proxied to rewrite IPs.
