L3 Switch & Sophos VLANs

I need remote assistance to finish the network build at one of our branch offices. The core is an unbranded Layer-3 switch that must be fully configured, then integrated with our Sophos firewall.

Scope of work
• Create and name 6-10 VLANs on the switch, adding SVI interfaces with the correct gateway addresses.
• Configure inter-VLAN routing on the switch so local traffic stays on-site.
• Establish a tagged trunk to the Sophos and map each VLAN to a matching interface or sub-interface on the firewall.
• On the Sophos side, add the VLAN interfaces, basic DHCP pools (where required), and simple firewall rules to let internal traffic reach the internet while blocking inter-VLAN access except for defined management networks.

Acceptance criteria
• End-to-end ping between devices in every VLAN and the internet.
• No unintended routing between user VLANs.
• Clean CLI / WebAdmin screenshots or saved configs supplied for both the switch and Sophos so I can archive them.

Remote session can be arranged via AnyDesk or similar at a mutually convenient time; I’ll have console access.

Additionally need to also configure proxmox host and networking with these
