Further updates to help hopefully.
Seems issue was noted here as well: ROUTE10 FAQs (and answers) - #78 by L3houx
WAN is on WAN1, and is running DHCP with VLAN10
Default IP range is 192.168.2.0/24 (LAN3 uses this)
I have the 10Gbit running on 10.10.0.0/16. - trying to run on the SFPs (tried both same result).
I’ve had to put the 10Gbit on a VLAN (100) as can’t seem to give specific interfaces an IP range.
I have a 200 VLAN for wifi kids network (can ignore for now, but exains why 200 vlan is in the below)
I have tried using WAN2 port, changing from “WAN” to “Standard” mode, in case it was a faulty SFP
