Cisco ASA: Allow VPN Traffic “Through” A Cisco Firewall
KB ID 0001428 Problem I got asked to put in a VPN for a client, this week, it went from a simple site to site, to a site to site with a Fortigate firewall at one end, to a VPN from and ASA to a Fortigate ‘through’ another ASA. It’s been a few years since I had to tunnel ‘through’ a firewall, and experience tells me, if you don’t have control of BOTH ends of a new VPN tunnel, anything that stops...
Cisco ASA – Remote IPSEC VPN With the NCP Entry Client
KB ID 0001260 Problem I’ve covered Cisco IPSEC Remote VPNs a long time ago, and I’ve also blogged about the Cisco IPSEC VPN Client Software.

VPN Problem Cisco PIX v6 to Cisco ASA 5500
KB ID 0000761 Problem I found this out purely by accident today, while replacing an old PIX 506E that had died with an ASA 5505. The client’s other site still had a PIX 506E (Running 6.3(5)). I was setting up the VPN, and noticed something that WOULD have been a problem if I had not spotted it. Solution Essentially the older PIX firewalls are set for 3DES encryption, MD5 Hashing and Diffie Hellman 2. After version 8.4 the ASA...
