PfSense router integrated into your network setup.
PfSense router integrated into your network setup.
You’re trying to isolate a pfSense router for separate network access while troubleshooting connectivity issues. The setup involves a VM on ESXi running pfSense, with virtual switches feeding internet traffic. You’ve adjusted firewall rules and VLAN settings but still can’t reach the internet. Since you’re in the DMZ of your ISP’s router, ensure the WAN interface is properly configured with VLAN Tag 2 and priority 3. Also verify that the pfSense VM has the correct IP assignments—both IPv4 and IPv6 should be active. If it still doesn’t work, consider keeping the pfSense in the DMZ for better isolation and monitoring. Double-check your routing tables and ensure no conflicting rules are blocking access.
Use a local LAN IP as the pfSense external/WAN link, avoiding the DMZ. Ensure both devices have routing configured—pfSense to the ISP router and the ISP router back to pfSense. This should resolve any connectivity concerns.
Begin by configuring the setup in Systems > Routing. Confirm whether displaying the ISP router’s IP as the WAN_DHCP Gateway is correct, or if you should adjust firewall rules instead. Your ISP router likely offers limited options such as port forwarding or DMZ settings.
Thank you! It seems the network configuration on the VM was mistakenly directing traffic to the ISP router instead of pfSense.
