I find from time to time I get non internal for both source and destination on one line as firewall hits. Line#1 has the "source" that is blocked from Spamhouse and the like as a hostile IP address and the destination in line #1 is some obscure. IP that has no info other then it is just some IP address. It is blocked so GOOD, but can someone tell me what is going on here as far as why one of the 2 are not one of my internal IPs?
