Scott,
  Thanks for the info.  The checkpoint sk ID sk25675.
   
  That being said, I performed "cpstop" on both the Active and Standby 
SmartCenter
  and edit the $FWDIR/lib/user.def file with vi editor.  I performed "cpstart" 
on both the
  Active and Standby SmartCenter after that.  The problem is that after the 
policy is
  pushed, I checked the user.def file again and it seems like the changes I made
  was not there anymore.  
   
  I looked at the sk solution again and it specifically stated that this 
solution is for
  NG AI and not NGx R61.  It seems to me that CP is doing something in NGx R61.
   
  Any ideas?  Thanks.

  I have seen some documentation from Check Point that allows excluding
traffic from a certain IP address to not be encrypted. The changes they
discuss in the user.def are

#define NON_VPN_TRAFFIC_RULES \

(icmp, src=212.150.30.22)


You could try setting it so traffic from the source and destination from the
VRRP address is not encrypted. So it should look something like the
following

#define NON_VPN_TRAFFIC_RULES \

(icmp, src=192.168.1.1)
(icmp, dst=192.168.1.1)

I am sure there is a better way to do this but it might accomplish
what you are trying to do.
