I guess this question will have been posted many times before so apologies in advance. I want to run VM's for Sophos XG and possibly OpenWRT and as both require multiple bridge setup, i.e. WAN & LAN I need to know how to configure these.
I use 5G broadband (not an off-the-shelf solution) but can configure the 5G module settings with AT commands. The LANIP address configured for the 5G module is 192.168.110.5 to 192.168.110.254 for DHCP purposes (I assume) with 192.168.110.1 as the gateway. The Proxmox web interface is on 192.168.110.11/24.
When all 4 ports on my server (enp1s0...enp4s0) are assigned to Linux Bridge vmbr0 I can connect my laptop via ethernet and access the internet. I then add a 2nd Linux Bridge vmbr1 and assign this to another subnet for a WAN connection (say 192.168.210.11/24) using enp1s0 (after removing enp1s0 from vmbr0). But when I plug my 5G feed into enp1s0 I immediately lose internet connection but still have LAN access.
So I'm clearly being really dim somewhere - my network skills are limited to linking devices on the same subnet and port forwarding to proxy server for my web apps when I used a standard ISP router and wired broadband prior to my move to 5G. As my servers back then only had one ethernet port I relied on UFW for firewall purposes.
If I could get the networking configured correctly and get Sophos XG running I then want to incorporate my Unifi Cloud Gateway Ultra and U6+ AP but want to take things one step at a time. N.B. by connecting my UCG to a port assigned to vmbr0 I also have working wifi but I want the internet source to ultimately be provided via the Sophos XG firewall too of course.
I really hope someone can help me implement a solution as I've tried different configs but with no success.
Thanks in advance
