| Dear All I think i have narrowed down the solution to why i am having problems with a simplified VPN install - Apprently the remote gateway is looking up the internal IP address of the smart centre server which sits behind the local gateway and cannot obtain the CRL - thats why i am getting an invalid certificate error message in the logs - apparently The checkpoint solution is to NAT the the smart centre servers destination private address to the smart centre servers public address on the remote gateways NAT rules What i mean is [test lab] remote gateway - external ip = 192.168.40.1 Local gateway - public ip = 192.168.30.1 Local gateway - internal ip = 192.168.5.1 smart centre server = 192.168.5.40 Problem The problem is that remote gateway cannot obtain the CRL (certification revocation list) from the local smart centre server located behind the local gateway Solution I apparently have to NAT from the remote gateway using the following method - Taken from checkpoint site For the remote gateway, the following network address translation rule should be placed at the top of the network address translation rules: ORIGINAL PACKET SOURCE: Remote gateway DESTINATION: <internal private IP address of management module> SERVICE: fw1_ica_services TRANSLATED PACKET SOURCE: = Original DESTINATION: <statically NATed IP address of management module> SERVICE: = Original The thing is it doesn't work - how do i get the remote gateway to perform destination NAT? When i fire up a connection the destination address is still that of the private IP address of the management server and not the NATTED public address - thus the connection drops at the router in the middle I can do this with hosts behind the remote gateway - as i think NAT is performed on the ingress NIC - but with the gateway the NAT is on the egress NIC as it can send remote traffic only one way! Has anyone done this before - its baffling me! Many Thanks PS - there is no XLATE DST in the logs ! Last edited by philofish; 2006-03-20 at 12:38. |
