'man 8 ppp' is up on my gateway box as I'm writing this post. I also read www.freebsd.org/en_US.ISO8859-1/books/faq/ppp.html and the other relevant docs at freebsd.org. I'm curious about the optional [-targetport], [aliasPort] and [-remotePort] above. I'm trying to dovetail these to an example given at the above URL, as follows: Red Alert example: nat port udp InternalMachine:8675 8675 Does the second '8675' refer to 'aliasPort'? When do you use the '-blah' format? Does the above 'nat' synopsis mean one can use either: nat port proto targetIP:targetPort aliasPort [remoteIP:remotePort] or nat port proto -targetPort -aliasPort [-remotePort] TIA... -- -duke Calgary, Alberta, Canada To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
