And just in case anyone was wondering, I am currently working on a ``nat config '' feature for ppp. I'm just taking lots of time determining the best way to do it, since there is a considerable amount of code from natd that needs to be added to ppp (in other words, the config file parser is around 25% of natd's total code.) -- Matthew Emmerton GSI Computer Services +1 (800) 217 5409 (Canada) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
