Mulhuijzen: Hi Roger, > What sort of changes are you talking about here? Maybe there's a different > way of going about it. I want to move an existing network from 91.0.0.0/8 to 172.16.0.0/16. Furthermore name resolution changes from wins to dns and dhcp is no longer used. The whole story has to take place during normal operation and I can not enter a gateway on any machine. It will take ~2 weeks and there are ~100 computers. I thought of using FreeBSD/ipfw/natd and two nics. One nic is in the 91.0.0.0 and the other in 172.16.0.0. Whenever a computer moves from 91.0.0.0 to 172.16.0.0 I define his old IP as alias on the freebsd-box. Natd forwards packets to the new IP. In the same way I define any IP of not-yet changed computers as alias on the 172.16.0.0 nic of the FreeBSD box. Name-Resolution should not become a problem because in the "old" net, wins stays active and in the "new" net I setup the dns. So I must add/delete/change natd rules frequently. I did never do such a thing before and I did not find any information how it could be done. If there are any books/webpages/whatever which cover the issue I would be glad to know. tia /ch -- "Contrary to popular belief, Unix is user friendly.
