Re: [External] org.apache.catalina.valves.RemoteAddrValve

It looks like you need to escape your periods, like you did for 127\. etc...
1\.3\.5

LOL, I'm decent at regex Robert.  I got the \d+ from what ships in the
context.xml:

127\.\d+\.\d+\.\d+

It looks like an attempt at saying localhost can get in as long as the
localhost IP starts with 127.  I assumed it wasn't actually regex but some
"tomcat language"...  Thanks for the education!  I'll jump back on here if
things don't work on the other side of the firewall...

Re: [External] org.apache.catalina.valves.RemoteAddrValve

You need to read up on "regular expressions" (or "regex").

In a regular expression, a lowercase "d" is a single decimal digit. A "+"
means one or more of them. A period means ANY character (which is why you
have to escape it when you mean "period"). A backward slash means to treat
the character immediately after it normally and not as a special character.
So "\d" would mean the literal letter "d".

There's more rules, but they're well documented all over the internet, so I
won't elaborate.

Sorry folks (Robert), but upon further testing, it looks like port 8080
isn't open on these IP's.  I was mistaking the attempt to connect from my
curl command with a response.  I withdrawal my question for now.  I'll
reply to this thread if it doesn't work once the hole in the firewall is
carved properly.  Thanks!

Thanks for the quick response Robert!  So I tried escaping the periods and
putting the \d+ for the * but it didn't work.  Is the \d+ incorrect in
substitution for *?
