Without a hash, it can be useless.
For example, the client initiates a TCP session:

• SYN is forwarded from the client to 10.0.0.7
• 10.0.0.7 responds with SYN/ACK to the client
• client sends ACK, which is forwarded to 10.0.0.2

set service pppoe-server authentication mode 'noauth'
set service pppoe-server client-ip-pool name foo gateway-address '192.0.2.1'
set service pppoe-server client-ip-pool name foo subnet '192.0.2.0/24'
set service pppoe-server interface eth1

Check

vyos@r14# cat /run/accel-pppd/pppoe.conf | grep "\[auth" -A 2
[auth]
noauth=1

Thanks for clarification @b-

This isn’t specific to WANs at all, no! I am using it for a WAN, so some of my comments reflect that, but really this is just a generic hook for any DHCP interface.

@b- Im not sure 100% sure whats happening, as I am not a developer... I saw your code samples and PR in git...

Should return an error, as this is not implemented.

I was wrong. NOT 6 CHILSD_SAs on one tunnel.
6 IKE SAs on one configured tunnel.

I met 2 issues after the last commit.

Awesome, I am glad to hear the provided info was helpful! Thank you for the quick investigation and explanation.

Again, thanks for the detailed reproducer; that made investigation straightforward. This appears to be simply an 'async' issue for FastAPI, the underlying web framework for vyos-http-api. FastAPI is very good at managing red/blue issues automatically, but in this case we need to explicitly annotate the endpoint method with async: an explicit lock does not appear necessary, though I will need to confirm. I'll provide a PR shortly. Thanks again !
