Hi list,

I've some strange problem with "connection being terminated"
while having open connection with Firewall-1 NG FP2 using GUI Policy Editor FP2.
Any help/hints/suggestions would be greatly appreciated!

Here is my setup:

#uname -a
SunOS 5.8 Generic_108528-15 sun4u sparc SUNW,Ultra-250

#fw ver
This is Check Point VPN-1(TM) & FireWall-1(R) NG Feature Pack 2 Build 52163

Sun has three network interfaces: two gigabit (ge0, ge1) and one 10/100 (hme0).

ge0 and ge1 go to the Nortel BayStack 450-24T switches (they have gigabit
adapters too). Those two Nortel switches organized into two VLANs.

hme0 goes to my ISP.

Here's my problem:

When I try to connect to Firewall-1 NG using Policy Editor NG FP2 (build
520146) everything seems to be OK. I pass authentication and can add/edit
network objects, monitor log messages and etc., BUT when I try to ping or
telnet something from GUI workstation while having open connection with
FireWall I immediately receive "Connection with FireWall has been terminated"
error message and in order to get connection again I have to cpstop/cpstart CP.
This _only_ happens when I connect to FireWall through Nortel switches (either
from VLAN 1 or VLAN 2).

If I connect to FireWall through hme0 (using crossover cable) everything is
fine.
I suppose that there is something wrong with gigabit adapters configuration.
Maybe TCP timeout settings?

Has anyone using Nortel BayStack 450-24T switches (with gigabit adapters) seen
this behavior? Any hints?

Thank you for your time.
Looking forward to hear from you.

Regards,
Roman
