Traffic Gathering /monitoring

TCPdump

ATRG -sk40072

FW Monitor

ATRG - 41045

Functionality

There are four inspection points when a packet passes through a Security Gateway:

Pre-Inbound - marked as 'i'

Post-Inbound - marked as 'I'

Pre-Outbound - marked as 'o'

Post-Outbound - marked as 'O'

Note:

The direction (inbound/outbound) relates to each specific packet, and not to the connection.

fw monitor -e 'accept src=x.x.x.x or dst=v.v.v.v;' -o filename.cap

fw monitor -e "accept;" -o /var/log/fw_mon.cap

fw monitor -e "((src=x.x.x.x , dst=y.y.y.y) or (src=y.y.y.y , dst=x.x.x.x)), accept;" -o /var/log/fw_mon.cap

fw monitor Examples:

# packets with IP 192.168.1.12 as SRC or DST

fw monitor -e 'accept host(192.168.1.12);'

# all packets from 192.168.1.12 to 192.168.3.3

fw monitor -e 'accept src=192.168.1.12 and dst=192.168.3.3;'

# UDP port 53 (DNS) packets, pre-in position is before 'ippot_strip'

fw monitor -pi ipopt_strip -e 'accept udpport(53);'

# UPD traffic from or to unprivileged ports, only show post-out

fw monitor -m O -e 'accept udp and (sport>1023 or dport>1023);'

# Windows traceroute (ICMP, TTL<30) from and to 192.168.1.12

fw monitor -e 'accept host(192.168.1.12) and tracert;'

# Capture web traffic for VSX virtual system ID 23

fw monitor -v 23 -e 'accept tcpport(80);'

# Capture traffic on a SecuRemote/SecureClient client into a file.

# srfw.exe in $SRDIR/bin (C:\Program Files\CheckPoint\SecuRemote\bin)

(not needed if you are testing a Remote Access VPN):

vpn tu

Then select the option that reads,

Delete all IPsec+IKE SAs for a given peer (GW)

enter your remote GW ip address

exit the utility

3. Try to build the tunnel back up again, in both directions,

attempt to connect from YOUR NETWORK to a device in

the remote encryption domain and then attempt to connect

from THE REMOTE NETWORK to a device in the local

encryption domain.

4. Turn off debugs

vpn debug ikeoff
