AWS Site to Site VPN not working

Oneal1975
Level 1
Level 1

I am at a loss as to what I am missing here. Help you be greatly appreciated

Here are the details (changes the private IP info for security reasons)

AWS Subnet 172.31.1.0/24

AWS Tunnel 1 Outside IP 52.53.76.26 Inside CIDR 169.254.87.0/30

AWS Tunnel 2 Outside IP 54.183.19.115

 

Internal Office Subnet 192.168.0.0/26

Office Public IP (Changed for security) 255.255.255.255

 

And here is the config that does not work:

 

crypto isakmp identity address
crypto ikev1 enable outside-comcast
crypto ikev1 policy 201
encryption aes
authentication pre-share
group 2
lifetime 28800
hash sha

group-policy filter internal

I am willing to figure out a way to pay whomever can help fix this $20.00

 

Thank you in advance

Make sure AWS accept only AES 128/256
