Replacing network switches can be a pain sometimes

One of those days when replacing 2 routers being used as switches should be so simple bit turn out so complicated. I completely forgot I’m using one of them as a “firewall” between a dmz and the rest of the network. Figured I’d just switch the IP on the comhem router and it would work for now at least, but no, it refused to because guest network is hardwired in the router to the same range as my internal network, and hence impossible to use… Winded up reconfiguring everything on my network to a different IP range, spending a couple of hours doing so, and once I’m done, switch IP on the comhem router and reboot it… And get a 10/8 IP address on the Internet side interface… Wtf? I call the tech support and apparently this has been so for at least 3 years. Sometimes you get a private network IP on the Internet, sometimes not, and there is nothing you or they can do about it. I went home and rebooted the router, and got an 83/8 IP instead this time. So… Something I planned to take 10 minutes winded up taking 5-6 hours… Hurray… I just wish we could start being sane and also that certain network providers would start implementing IPv6.
