Virtual Private Networking

B-11

The IKE Phase 2 parameters used in Scenario 1 are: 

•

TripleDES

•

SHA-1

•

ESP tunnel mode 

•

MODP group 1 

•

Perfect forward secrecy for rekeying 

•

SA lifetime of 28800 seconds (one hour)

Once you have completed the VPN configuration steps you can use PCs, located behind each of 
the gateways, to ping various addresses on the LAN-side of the other gateway.

You can troubleshoot connections using the VPN status and log details on the Netgear gateway to 
determine if IKE negotiation is working. Common problems encountered in setting up VPNs 
include:

•

Parameters may be configured differently on Gateway A vs. Gateway B.

•

Two LANs set up with similar or overlapping addressing schemes.

•

So many required configuration parameters mean errors such as mistyped information or 
mismatched parameter selections on either side are more likely to happen.
