Hello list, We're running IPCop v1.4.0a10 on a DHCP ADSL connection. Snort is the IDS software installed. I took a look-see at my firewall log for yesterday and saw four instances of what appears to be reversed incoming RPC traffic on the Red (WAN/eth2) side. I had this sort of a scenario before, but it was reversed port 80 traffic. I Googled to no avail, and I also reported it to this list and never was able to figure our what the heck causes this type of traffic, so when it cropped up again I'm still at a loss - any clues?
