Hi all,
I saw some similar posts but without a conclusive answer for me, so I'm going to ask this question once more.
My service provider provides 2 vlans via the NTU (FTTH) to my switch (vlan 4 and 6). Vlan6 provides internet (via PPOE) and vlan4 provides IPTV via IPv4 multicast.
In my setup the NTU is connected to a cisco 3550 switch and my opnsense hw appliance (v 21.1.6) is connected with interface igb3 to the same switch. The switch provides opnsense a trunk and therefore 2 vlan interfaces are configured on the opnsense appliance.
In this setup, my first created interface (internet via ppoe) connects, so you'd say vlan tagging etc all is working.
However; iptv does not receive an IP address.
So I changed the setup of the switchport connected to opnsense, providing the default vlan as 4 (thus untagged). It does not seem to make a difference until I reboot; in that case IPTV vlan4 interface receives an IP address and the ppoe connection cannot be established.
During my troubleshooting I have discovered the same mac addresses were active on both vlans; i installed the patch for that (55f54f8), configured dummy mac addresses and indeed.. that part is working properly now but still no DHCP address lease via VLAN.
I do not have IDS/IPS active so that cannot be my issue. I would appreciate any further troubleshooting tips!
