Firewall log proto/protoname to rule protcol mapping [solved]

[binaryanomaly]

Hi,

In the live log I see that a connection gets blocked:

Code: [Select]

proto 0
protoname ip

Now I want to create a rule that allows this.
But I have no "ip" only protocol I could select nor a number "0" in the rule creation UI.

How can one translate the protocol mentioned in the log to the ones available for the rules?

Edit: As it does not appear in the logs atm it seems that my guess for IPV6-ICMP may have been right - but how could I determine without guessing?

OK, it seems that

Code: [Select]

proto actually is the "ip protocol number" in the ipx header field (https://en.wikipedia.org/wiki/IPv4#Header).

Therefore the translation table here can be used:
