Modem Access

As you have noticed, after setting your WAN interface to PPPoE, you don't have access to your modem/router webUI.

We have to add an interface and enable outbound NAT for that interface. Let's fix that.

Navigate to Interfaces -> Assignments

Interface

If your WAN interface has selected Network port: pppoe0(igc0).

• Select next to New interface the igc0
• Click ➕
• Click 💾Save
• Click on the newly created interface

• Check Enable Interface
• Check Prevent interface removal
• Description: Give it a meaningful name (eg. ISP)
• Uncheck Block private networks
• Uncheck Block bogon networks
• IPv4 Configuration Type: Static IPv4
• IPv4 Address: Use an IP from the modem/router of your ISP (eg. 192.168.1.150 / 24)
• Click Save
• Click Apply Changes

NAT

Navigate to Firewall -> NAT -> Outbound

• Select Hybrid outbound NAT rule generation
• Click Save
• Click Apply Changes

• Click ➕
• TCP/IP Version: IPv4
• Protocol: any
• Interface: ISP (or the name you gave before)
• Source address: LAN net
• Source port: any
• Destination address: ISP net
• Destination port: any
• Translation Address: Interface Address
• Click Save
• Click Apply Changes

You should now have access to your modem/router webUI!
