Dear All,

I have one checkpoint NG3 in my company and verifying in Tracking i have
tousands of events with ICMP type 8 and type 17.

The events has origin in my internal networks, with one problem .. the
Source IP is my PAT address for internal hosts to internet.

Is there any bug of Checkpoint? Anyone already seen this event?

I will go verify with sniffers and other tools, but this IP (Only for PAT)
is no routeable in my internal networks...

Thanks for attention.

hi,

perhaps related to:

Sniffer: depends on what platform you use:
- Solaris: snoop
- everything else: tcpdump

Reading out the MAC adresses of there packets should give a clue in the 
direction where to search further.
