L3 Switch & Sophos VLANs

@farooqtahir2013

With over a decade of work experience in the realm of Network Administration and System Security, I have garnered extensive knowledge in handling and configuring the very nuances you've highlighted in your project. Having dabbled with multiple vendors, including Cisco (whose proprietary networks run layer-3 switches similar to yours), configuring LANs, VLANs, VPNs and ensuring no unintended routing has become second nature to me. With my expertise, setting up the tagged trunk between your Layer 3 switch and Sophos Firewall for inter-VLAN routing and controlling user access will be a breeze. I am also well-versed in Virtualization techniques using Proxmox among others, familiar with cloud computing (including AWS which offers great scalability), and skilled in working with Linux servers. Alongside network infrastructure planning, design, and implementation is my strong suit too. Hence, I can also promise you efficient assistance in configuring the Proxmox host and networking for your convenience. Your project presents a perfect amalgamation of my skills which makes me confident about completing it as per your requirements within your timeframe. My commitment to delivering quality results paired with an unwavering availability gives you the assurance that I can promptly attend to any queries or concerns that may arise during the project execution. Let's ensure a seamless network build for your branch office together!

Hi there, I see you need a Layer-3 switch fully configured with 6-10 VLANs, inter-VLAN routing, and a tagged trunk to your Sophos firewall, plus basic DHCP and firewall rules. I can handle this end-to-end, including the Proxmox host networking. What I'll do: ✅ Configure all VLANs, SVIs, and inter-VLAN routing on the L3 switch. ✅ Set up the trunk to Sophos, map VLANs to firewall interfaces, and add DHCP/firewall rules. ✅ Test end-to-end connectivity and block unintended inter-VLAN traffic. ✅ Provide clean configs and documentation for future VLAN additions. Skills: ✅ Sophos firewall configuration (interfaces, DHCP, rules). ✅ Layer-3 switch VLANs, SVIs, and inter-VLAN routing. ✅ Proxmox host and network setup. ✅ Microsoft® Certified: MCSA | MCSE | MCT ✅ 300+ projects delivered, 280+ five-star reviews. I’m available 24/7 and will work until everything is perfect. Quick question: Do you have a specific IP scheme for the VLANs, or should I propose one? I can complete this in 3 days for ₹7,000 and start right away.

Hello, I can assist you remotely to configure your Layer-3 switch and Sophos firewall. My plan is to access your branch setup via remote session. I can create the requested VLANs on your Layer-3 switch and configure the SVI gateway IP addresses. I can enable IP routing and configure an 802.1Q tagged trunk port connecting to your Sophos firewall. On the Sophos firewall I can set up matching sub-interfaces, configure DHCP pools for each VLAN subnet, and write firewall rules that grant internet access while blocking inter-VLAN traffic outside your management network. I can test end-to-end ping connectivity across all VLANs and provide full CLI configurations alongside a documentation guide for adding new VLANs. 1) Is your Sophos firewall running Sophos XG XGS firewall software or the older SG UTM software? 2) Does your unbranded Layer-3 switch use a Cisco-like CLI syntax or a web management interface? Thanks, Bharat

I recently helped a client successfully configure their Layer-3 switch and integrate it with their firewall, ensuring a seamless network build. I will assist you in creating and naming VLANs, configuring inter-VLAN routing, and establishing a tagged trunk to your Sophos firewall. Let's schedule a free consultation and fast track the project to get things moving immediately. I noticed you require clean documentation and end-to-end connectivity tests. This shows your commitment to a professional and user-friendly setup. I offer extensive experience in network configuration and can begin right away, delivering a quick action plan to meet your needs. Could you confirm the preferred software or tools for the remote session? Regards, Quinlann.

Hi, I can handle this project end-to-end, including the Layer 3 switch configuration, VLANs/SVIs, inter-VLAN routing, Sophos VLAN interfaces, DHCP, firewall policies, trunking, and full connectivity testing. I can also configure the Proxmox networking and integrate it properly with the VLAN design. I’ll provide the required screenshots/saved configurations and clear documentation for the final setup, including steps for adding future VLANs. Additionally, I can review the design and implement improvements where supported, such as LACP/EtherChannel, link redundancy, load balancing, VLAN segmentation, and routing/firewall optimization. I’m available for remote work via AnyDesk or similar and can work with the available console access.
