ok here are the results:
1. No internet connectivity with both WANs plugged in. If I remove one I can then get out
This seems to be working OK now.
2. VPN, I can connect and ping internal devices but cannot RDP to those same systems
I can still connect, but now I cannot even ping anything
3. Once I do have things working, getting DHCP from my internal settings I can no longer get to the IP Address of the ERPRO unless I go back to static IP of something in the same range. But I can ping it :/
Same issue still exists
Using DHCP on my laptop, I get "Unable to load the router configuration"
4. Guest Wifif on VLAN 20 works fine, but our inhouse (No VLAN) does not get an IP Address
Inhouse now gets an IP but VLAN 20 with ip 192.168.100.10 can now see all the networks, that would be bad :/
