Being new to this, I stuffed up somewhere and need some pointers...
When I first set up the UTM (home) it was getting DHCP from my router. A .10 address for the internal and a .30 for external (WAN). (Same network obviously)
I ended up configuring the UTM to provide DHCP service so that the default gateway of devices would be the UTM - the .10 address. Then I disabled DHCP on the router. All was working well, and as devices renewed their IP's, they'd get it from the UTM and start routing traffic via it. Schweet :)
Then I rebooted the UTM to increase the memory - its running as a VM and I wanted to take the memory from 2GB to 4GB. When it came back up, the WAN interface was down. It had gotten a DHCP address from the UTM itself so now was pointing to the .10 address and making a loop I guess.
So...I changed the External WAN to be static .30 and set the default gateway to the router. Services restored, yay :D
But.....it looks like it isn't actually working properly. I've kicked off a restore from crashplan and see this:
It looks like the download is operating over internal NIC only, and not being passed via the WAN NIC.
How do I fix it? I almost added the WAN address as the default gateway of the internal NIC, but I fear that may cause me to lose connectivity via the web admin page and then I wouldn't be able to fix put it back
Additional traffic data;
It looks like the *backup* to crashplan was routing as expected (ie outbound traffic) so it is the download traffic (restore) that is for some reason coming straight from the router to the internal interface of UTM
