So the thing is, I've attempted to give my Archer C6 v2 US (21.02.2) internet via PPPoE in Australia (Tangerine Telecom) through a Telstra Modem F@ST 5535. I did set it to bridge mode and all that.
The problem is, even when my C6 is connected via PPPoE, it doesn't give any internet access when using eth0.2; I've even resorted to trying MAC Spoofing to see if it's a MAC Lock by the ISP, and even then it's a no go.
At this point, I'm stumped on what to do. If there's anything noteworthy, the connection on the modem is done through PPP. I did use PPPoE as what the ISP instructed, but now I'm fresh out of ideas.
Oh, just more information. When the modem is connected to the internet, it has an IP of 1xx.xxx.xxx.xxx; when it's the C6, it's 5x.xxx.xxx.xxx and that has no internet.
Tangerine Telecom says it's VLAN 100. Wait, how do I enable that now that DSA's the architecture being used? There's no switch menu item anymore in the current release of 21.02.
I'm still not fully familiar with the new software architecture, so help would be really nice.
Right. Given that, I'll have to study a bit on DSA. I'll give an update as to my progress later.
Whelp, the progress is unfavorable thus far. I am getting a connection with the PPPoE with the IP 5x.xx.xxx.xx, and even then there’s still no internet. Even did the VLAN ID thing and all.
Accordingly you're missing the (old-style) swconfig switch configuration for WAN/ VLAN 100, at least something like
config switch_vlan
option device 'switch0'
option vlan '100'
option ports '0t 1t' # <-- I have no idea if wan is hardware switch port1, adapt as necessary
option vid '100'
Likewise you also need to drop your WAN switch port from the corresponding VLAN1 (switch_vlan) definition.
