[FW-1] why there is only one way connection?

["Sim, CT (Chee Tong)" <CheeTong.Sim@FW1-NOSPAMSIN.RABOBANK.COM>]

Hi.. ,

I had a Check Point Firewall-1 4.0 installed in a Sun Box and it is located
in our bangkok branch (the other side of the WAN).  I had a problem that I
can't solved.  From our workstations in Singapore, I can ping to the the
Firewall in bangkok, but from the bangkok firewall, I can not ping to any
workstations in Singapore, but it can ping to those workstations in Bangkok
Could you please tell me what could be wrong?

Besides a few more question,
1)If I enable a rule in Firewall   source:A Destination:B  services:(ICMP)
Action:Accept, it make A can ping to B, does it mean that the rule also
enable B to ping to A?

2)I saw the properties of FW implied rule, there are something like 1)Last
2)First 3)Before Last   What is the meaning?

Thank you very much
CT
