Description

See attached screenshot. When I put a port number, like "25" in the 'destination port' field, I would expect to get matches to that exact port. But instead it's also matching substrings, like port "12539", "2570", etc.

I don't really care about random ports that are closed anyway, but I do care to see what's happening on my mail port. So even if this is deliberate, it would be nice to have an exact port matching option. I guessed possible syntaxes like "25" or +25 but they didn't work.
