I am switching ISPs, and of course, this means total readdressing. I have not done this for quite some time.....
I seem to recall, back in v4 that I had to rebuild EVERYTHING. I had to start fresh with all new DNAT rules, filters, everything, as I was locked out of changing Interface addesses with until everything dependent on the addresses were removed.
So now I am on v 6.011. I don't see myself adding an upgrade to v7 with everything else I need to do (even with it supporting OSPF and that might be of value).
So a search here did not reveal any help/experience in re-addressing.
