PPoA Connection to ISP

Installing and Using OpenWrt
1

Hi all,

I'm on OpenWrt Chaos Calmer 15.05.1, I know it's ancient - but it came with my router. I'll look to upgrade at some point, but that's for a later date.

I'm trying to configure my new router as a router + modem so that I don't need the modem provided by my ISP anymore (Sky). I've read here, how this needs to be done for Sky ADSL https://openwrt.org/docs/guide-user/network/wan/isp-configurations#adsl3

Here is what I added to my /etc/config/network file, based on the above.

config dsl ‘dsl’
option annex ‘a’
option tone ‘a’
option xfer_mode ‘ptm’
option line_mode ‘adsl’

config interface ‘wan’
option _orig_ifname ‘eth0’
option _orig_bridge ‘false’
option proto ‘pppoa’
option encaps ‘vc’
option atmdev ‘0’
option vci ‘38’
option vpi ‘0’
option username ‘myusername’
option password ‘mypassword’

However, for some reason this still doesn't work; this is what I'm now seeing in the syslog:

Sat Jan 30 22:20:51 2021 daemon.notice netifd: Interface 'wan' is setting up now
Sat Jan 30 22:20:51 2021 daemon.info pppd[28016]: Plugin pppoatm.so loaded.
Sat Jan 30 22:20:51 2021 daemon.info pppd[28016]: PPPoATM plugin_init
Sat Jan 30 22:20:51 2021 daemon.info pppd[28016]: PPPoATM setdevname_pppoatm - SUCCESS:0.0.38
Sat Jan 30 22:20:51 2021 daemon.notice pppd[28016]: pppd 2.4.7 started by root, uid 0
Sat Jan 30 22:20:51 2021 daemon.err pppd[28016]: connect(0.0.38): No such device
Sat Jan 30 22:20:51 2021 daemon.info pppd[28016]: Exit.
Sat Jan 30 22:20:51 2021 daemon.notice netifd: Interface 'wan' is now down

Does anyone know what I might be doing wrong? Many thanks in advance!

What is the make and model of the router?

It's the Gli.net Convexa-B (GL-B1300)

This device does not come with a built-in xDSL modem.

Ah, that explains it. I'll just connect it to my existing modem then. Thanks for the help!

Please, keep in mind that you then either need to run that modem in bridge mode and operate PPPoE on your router, or run PPPoA on the modem, but then the modem will also need to operate as your primary router. The point being, PPPoA can only be used on a device that actually has a real ATM interface...

Thanks, understood. Just set up option 2, I think that's fine for my purposes. Appreciate the help!
