Hi,
i am currently trying to set up vpn between my checkpoint ng+ai, running on
sparc solaris, and a cisco pix. it does not work at first go. so tried to
use snoop to see whether there are any IKE related packets originated on my
site or coming from the vpn endpoint. i tried the following (just assume
10.10.105.2 is the external nic of the fw):
snoop -r -V from 10.10.105.2 or to 10.10.105.2
i did a telnet from outsite and snoop showed me this incoming packet
correctly even if the rulebase is blocking such packets. when i try to make
any connection from a host on my site to a host on the other site of the vpn
tunnel, nothing happens. snoop remains mute and after a while, about a
minute sometime a little bit more, i get the following error:
