So you have basically two possibilities: 1. Perform NAT on the router itself, provided it can (I guess it doesn't) 2. Connect the FreeBSD box directly to the Internet, i.e. replace the router with it - that's what I'm doing at our site (medium business). Depending on the interface your router has to connect to your ISP you may need to obtain a sychronous communication adapter - we are using SDLComm's N2, i.e. the FreeBSD 'sr' device. Let me know if I can help you in case you choose the 2nd variant, though it's nicely documented in the FreeBSD Handbook and natd(8). > Thomas Uhrfelt Cheers, Thomas -- ========================================================== Thomas Seidmann Simultan AG, CH-6246 Altishofen, Switzerland mailto:tseidmann@simultan.ch tel +41.62.7489000 http://www.simultan.ch/~thomas fax +41.62.7489010 ========================================================== To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
