I have a slight issue. I think it can be done, but am not 100% sure, since im 2000 miles away from the machines if the slightest thing goes wrong the nearest g uy is about an hour drive ..so i need to ask before i do :)
In the comming weeks(hopefully this week) we have to change over to a new Class C.. My main server that handles the websites has about 60 eth0 aliases. I want to be able to duplicate all those on the new class C, and use ipfwadm (or rinetd if ipfwadm cant do it, i fear rinetd wont handle the load that well !) to forward requests from the old ips to the new ones for the period of time that the DNS servers are updating(a few days at most i'd imagine) same for my mail server.. mail requests on the old ip would be forwarded onto the new ip. What i fear most is the moment when i try to add the route for the new network. anything special(is it possible?) i have to do to get 1 ethernet interface to have routes to 2 different networks? (both on the same router) im just scared if i add the new route, i lose connection and the machine's routing table will be screwed. While not a huge problem i hate downtime more then the other admins at this place! as for the firewall/forwarding, i found this on a website ..i think this is about what i'd need. ipfwadm -F -a accept -b -P tcp -S <old ip> -D <new ip> that look right ?? the machine is a dual p2-233 so i think it will have no problem with the extra firewall rules(already got about 60 in here) i tried playing with it, but i dont have any other networks that are local, everything else is bound to other devices in other cities:( thanks for any/all suggestions anyone can provide :) nate ----------------------------------------[mailto:[EMAIL PROTECTED] ]-- Vice President Network Operations http://www.firetrail.com/ Firetrail Internet Services Limited http://www.aphroland.org/ Everett, WA 425-348-7336 http://www.linuxpowered.net/ Powered By: http://comedy.aphroland.org/ Debian 2.1 Linux 2.0.36 SMP http://yahoo.aphroland.org/ -----------------------------------------[mailto:[EMAIL PROTECTED] ]-- 9:49pm up 89 days, 9:23, 2 users, load average: 1.44, 1.53, 1.57
