The comment above tcp_mss() says: * NOTE that this routine is only called when we process an incoming * segment, for outgoing segments only tcp_mssopt is called. So, it won't be called for frames created by ip_output() :-) To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

Check out the handbook. Specifically the part about natd. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

There are lots of ways to do this. It sounds like you want to want to route from a private (RFC1918) network to/from the public Internet. Right? To do that (successfully), you'll need to do some kind of translation. You likely won't need to do any routing at all, except to set a default route to your gateway, on all internal hosts. Do some reading on NAT (network address translation). natd(8) would be a good place to start. There are also plenty of web-based tutorials and documents that you can find by doing some web searches for the terms I've mentioned here. It sounds like static NAT may be the way to go in your case. Also, to ease in the configuration of each internal host (if you have more than one or two), consider using DHCP. (isc-dhcpd), to dynamically configure the network settings per host. That being said, I'm just guessing at what you're really trying to do. If I've guessed incorrectly, please reply with more detail. ;-) Thanks, - Ryan -- Ryan Thompson <[EMAIL PROTECTED]> SaskNow Technologies - http://www.sasknow.com 901-1st Avenue North - Saskatoon, SK - S7K 1Y4 Tel: 306-664-3600 Fax: 306-244-7037 Saskatoon Toll-Free: 877-727-5669 (877-SASKNOW) North America To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
