Hi,
  =20
  I am having a strange behaviour with a Cisco PIX Firewall Version 6.3(5=
). The configuration is done , the VPN are created between the 2 differen=
ts sites. The probl=E8me is after 5 to 6 hours of running, the ping to th=
e remote hosts doesn't go through. When i try to ping a remote host, I se=
e the followings line in the debug icmp trace:=20
  =20
  -request from inside:10.102.158.152 to 10.5.113.142 ID=3D512 seq=3D5376=
 length=3D40
44: ICMP echo-request: translating inside:10.102.158.152 to outside:10.10=
2.158.152
45: ICMP echo-request from inside:10.102.158.152 to 10.5.113.142 ID=3D512=
 seq=3D5632 length=3D40
46: ICMP echo-request: translating inside:10.102.158.152 to outside:10.10=
2.158.152

  And When remote host try to ping a local machine, i can see the request=
 coming without any reply.=20
  =20
  To get the ping work , we have to reload it.=20
  =20
  Do you have any idea? =20
