Hi, the reason why the modem does not show up is because usb0 interfaces do not match the prefix we use to distinguish between interfaces.

Tested successfully! Modem showed up as usb0 in ip link, but not in show interfaces.

Added requested config option to Kernel for 1.4

This has a simple fix: starlette commit c568b55d set the attribute

Request._form = None

to support use of Request.form() as a context manager. Since we override the Request class for backwards-compatibility support (translation) of form-data requests, we need to check for value, not existence, of the attribute. Adding this fix allows updating FastAPI past 0.91.0.

This has not been seen subsequently. Close unless recurrence.

FYI When I was troubleshooting I used:

In Both version, restarting relay service solved the issue:

I can confirm this behavior, which occurs when changing IP address on listening interface (where dhcp-discover is captured).
Issue present in 1.3.2 .
It's also present in latest vyos-1.4-rolling-202302140317, regardless if old interface syntax is used, or if new upstream-interfces plus listen-interface commands are used.

You can either run both address-families through one tunnel

Can you provide this configuration on both setups:

show config comm | grep relay

# And route to relay server
show ip route <relay_server>

@sdev @c-po @Alfa80 Can we look at rolling this back until it works fully, or fixing it so that it allows the above scenario please? Newer versions of 1.4 are unusable for me for a few months due to this. Let me know if I should file a separate bug.

accel-ppp doesn't support FQDN for RADIUS https://docs.accel-ppp.org/en/latest/configuration/radius.html#radius
So it is impossible until it is available in the accep-ppp
