Jason, Have you tried netcat instead of telnet? Can you do a tcpdump to analyze the packets?

I am putting linux servers at different locations across the country. The customer is required to open ports 7000-8000 inbound and outbound for our proprietary client to communicate. It is encrypted ftp traffic. The normal test procedure is to telnet from a windows laptop to port 7000 at our noc. This works fine with the windows box, but then fails with the linux box. Same IP used for both. The issue was repeated at a second location using checkpoint fw. I don't use/own any checkpoints so getting support is difficult. The problem seems related to linux and high ports (I am using 7000-8000) with checkpoint FW, lower port ranges work fine. I have been able to telnet from our noc to the target with windows and solaris, but not linux. Is there a something that is missing in the checkpoint config? Is this a known issue? Jason Lewis http://www.packetnexus.com It's not secure "Because they told me it was secure". The people at the other end of the link know less about security than you do. And that's scary. _______________________________________________ Firewalls mailing list [EMAIL PROTECTED] http://lists.gnac.net/mailman/listinfo/firewalls _______________________________________________ Firewalls mailing list [EMAIL PROTECTED] http://lists.gnac.net/mailman/listinfo/firewalls
