It adds no extra data. I never messed w/ NAT enough to have learned this. There's always something to learn! Thanks to all who responded.

Does NAT increase the overall datagram size? I thought it just changed addresses and stored connection information in a table somewhere. If this is the case, just having NAT, even 2x, isn't going to make it any more likely that your traffic will fragment. -Will ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
