Just fixed it, it’s working again.
Rene,
In configuring an ISAKMP Policy, Phase-1, one of the negotiable attributes in the policy is the Diffie-Hellman Group x. Where x is a number. What does the x (number) represent?
Thanks!

Hi Joey,
It’s the DH group number which basically is the strength of the key that we use in the DH key exchange. Higher group numbers are more secure but take longer to calculate:
DH Group 1: 768-bit group
DH Group 2: 1024-bit group
DH Group 5: 1536-bit group
DH Group 14: 2048-bit group
DH Group 15: 3072-bit group
DH Group 19: 256-bit elliptic curve group
DH Group 20: 384-bit elliptic curve group

Hi Michael,
Take a look at this video (start from 2:39):
https://www.youtube.com/watch?v=YEBfamv-_doIt explains the same process but with the math, I think that will be helpful.
