Checkpoint blocking microsoft.com and msnbc.com etc
I'm new to Checkpoint firewall.
I just installed Checkpoint NG R54 on Windows 2000 server.
Following is the connection.
Internet -- Cisco --- Checkpoint -- Local Network
Cisco does the NAT but firewall only does routing and firewall stuff.
I can go almost all the websites except following
Based on Ethereal on my machine,
1. TCP 3-way handshake is completed
2. Client sent HTTP GET (twice)
3. microsoft.com sent back an ack ([TCP Previous segment lost] as by
4. Client sent TCP RST
and that was it.
I've 2 rules
1. source (local subnet), destination (any) accept
2. any, any drop
I do not see any error in SmartView tracker.
Other than two sites that I mentioned above, I'm able to access all the
web sites as far as I've tested.
When I bypass Checkpoint by moving client machine directly behind the
Cisco router, I can go to both microsoft.com and msnbc.msn.com.
Thanks in advance ..
Re: Checkpoint blocking microsoft.com and msnbc.com etc
I was just wondering whether you had resolved this issue at all?
We have recently installed 2 UTM-1 and are experiencing this exact issue.
So far Check Point have not been able to find out the problem.
