Can this XG135 (SFOS 18.0.5 MR-5-Build586) model accommodate two ISP ?

Hi, Thanks for reaching out to Sophos community.

Yes it can accommodate two ISPs as long as there's a free port available to connect the ISP on the firewall.

Can this SOPHOS FIREWALL accommodate two ISP? I just want the community to view the ports at the back of the device

The labels on the ports match the default settings of the firewall but you can program any of the eight network ports for anything you want. For example, you could make port 4 a second WAN port, so ports 2 and 4 would be for your two ISPs. This is only an example.
