Sure thing

So that rule is attempting to extract any TWO ipv4 addresses detected in
any form of syslog message. So to give you some examples of when that
occurs, we'll look to Cisco firewalls/routers


%ASA-4-106023: Deny tcp src inside:192.168.3.79/57577 dst outside:

%ASA-7-710006: EIGRP request discarded from 192.168.23.1 to
inside:224.0.0.10

If I take the regex I wrote in this rule (as per first email), replace '\\'
with '\', then the regex works fine via egrep. It's a simple "when, do
this" type statement: I can't see what's gone wrong in it

I have another pipeline with two rules and it's working just fine - it
seems to be the regex in this that is at fault, but I can't see how
