6100 initial setup problems - enabling DHCP on all 4 LAN ports

Weird - I did that and used a different network... ok - starting from scratch and maybe this time through it will all make sense.

So to recap.. from default config...
Interfaces - create bridge group and add lan2-4
create interface (default name is opt7) and assign it to the bridge group

on wan2 - assign static ip / different network / and should then appear as option for dhcp server (change default from /32!!!)
firewall rules - copy LAN to Wan2/Management interface

So now - im getting my dhcp ip on the management interface but still unable to go anywhere - what checkbox am i missing now?

@Username00 said in 6100 initial setup problems - enabling DHCP on all 4 LAN ports:

firewall rules - copy LAN to Wan2/Management interface

The default LAN rule uses 'LAN subnet' as the source but that's not valid on the WAN2/MGMT interface. So if you just copied it it will not pass traffic. Change it to 'WAN2 subnet' or any.

AHHH - that's what that means!
OK - So now I'm good on Management - now I'm in the process of moving the LAN config over to the LANBridge.

And I wound up breaking Management and the bridge..... (that default /32 on static ip got me again)

OK - I figured out via .xml how to migrate my static dhcp reservations from LAN to LANBridge - and now I think I'm good to go.
Holy crap!

OK - going to save this config - start from scratch to make sure I didn't miss anything - then hook it up.

Next stop - Wireguard - (but that will be a different thread)

Thanks!

If you eventually reassign LAN to bridge0 the static DHCP leases and firewall rules etc would all follow that.

But, yes, it's super easy to get locked out whilst setting up a bridge (ask me how I know!). Having the mgmt interface available to connect to whilst you get the bridge configured makes it much easier.

What was interesting was that the dhcp config from LAN did not follow over - but it was still present in the .xml file. So easy enough to copy those entries from <lan> to <opt7>.

Lots of good gotcha items - and will post a nice document here once I've got it all sorted out for others to use.

If you had to copy it to opt7 then you had not yet re-assigned lan as the bridge0 interface. Once you do that everythign that was applied to the original LAN interface would apply to the bridge and hence all the bridged interfaces.
