Cisco Router – Configure Site to Site IPSEC VPN
KB ID 0000933 Problem I’ve done thousands of firewall VPN’s but not many that terminate on Cisco Routers. It’s been a few years since I did one, and then I think I was a wuss and used the SDM. So when I was asked to do one last week thankfully I had the configs ready to go. I’m going to use the IP addresses above, and my tunnel will use the following settings; Encryption: AES. Hashing: SHA. Diffie Hellman:...

Below I will add our switch into ISE, as a RADIUS device and create some groups, and locations for...
Site to Site IPSEC VPN from SonicWALL to Cisco ASA
KB ID 0000357 Problem You want to put in a secure IPSEC VPN tunnel from a Cisco ASA Device to a Sonicwall Firewall.
