I have a question for all you ISDN users who use an isdn router for there connection to the internet. What I need to know is if this connection scenario would work. ==isdn line===E Router ===E Computer #1 w/ freebsd & firewall \|/ HUB / \ /` '\ Computer #2 Computer #3 Say I had 4 ip's. My router was 1.1.1.1, #1 was 1.1.1.2, #2 was 1.1.1.3, and #3 was 1.1.1.4. On #1, would I make the gateway 1.1.1.1 (the router), and then on #2 and #3, make the gateway 1.1.1.2? What if I then got 1.1.1.5, and 1.1.1.6. Could I assign those two IP's to my FreeBSD machine using ifconfig, and then that is all. Or do I have to configure that in my router. Now, if I had the basic setup, ___ #1 ===isdn line====router====hub==='--- #2 `--- #3 With the router, could I filter out ALL incoming TCP connections to computers 2 and 3, but allow everything except icmp packets to #1? (deny icmp all around, and tcp on 2&3) Now, for this setting, with the same IP addresses, would my gateway on them all be 1.1.1.1, and then just assign the ip addresses like normal?
