Hi Folks 1. This is off topic, I believe, but when you get a chance key on. 2. Question is which are the good books out there which address troubleshooting VPN/IPSEC troubleshooting ? 3. Any good URLS/ resouces ? 4. I was recommended " Technical Guide to IPSEC VPN - James S Tiller" by a VPN guru and just picked it up. Anyone read any good books ? Thanks Pradeep
