We have a VPN setup with two static routes
10.254.18.0/24
10.254.19.0/24
We have a problem that we can only ever communicate from AWS - to one of the above blocks at a time. At some times it is .18 and at other times it is .19 - I caot figure out what is the trigger.
I never have any problem communicating from either of my local subnets out to aws at the same time.
Kinda stuck here. Any suggestions?
What have we tried? Well the 'firewall' guys said they dont see anything being blocked. But I read another post here that stated the same thing and the problem still ended up being the firewall.
Throughout the course of playing with this the "good" subnet has flipped 3 times. Meaning
- Right now I can talk to .19 but not .18
- 10 min ago I could talk to .18 but not .19
It just keeps flipping.
