I need to parse difficult traffic with Layer 2 Tunneling Protocol:
Eth->IP->UDP->L2TP->PTPP->IP->TCP->...
.. and get inner and outer IP addresses.
I use loop over layer->getNextLayer()) and it stops after first UDP.
Is there any BestPractise to cope with L2TP?

Thanks in advance

This is because L2TP isn't supported by PcapPlusPlus. Unfortunately there's no way around it, but to add support for it. Would you consider implementing it? – seladb Oct 18 '22 at 07:54
