Looking for clarity on site-to-site VPN connetions


Hello all,

My apologies if this is not the correct forum section but it seemed to be the closest to my questions.

In looking at our needs upcoming I may be configuring several site-to-site VPN connections from several different customers. I was a little concerned that the limitation on S2S VPN was 10 per VPC. I could not find any forums/docs or general Googling that made it clear if there was a way to increase that number by a support submission or if it was at all possible. If anyone has any info on my questions below I would greatly appreciate some clarity.

  1. Is it possible at all to increase the number of S2S VPN connections per VPC?
  2. Region limitations state that there is a maximum of 50 S2S VPN connections per region. Is that based on the default 5 VPNs (10x5)?
  3. If we paid to increase the number of VPCs from 5 to 6 would that mean our new region limit is 60?
  4. What if any alternatives are there for us who may need a large number of VPN connections to various customers?

Thank you in advance,
(D '.' )==D

It appears that AWS allows you to Request Service limit increase for both VPN connections per Region and VPN connections per VPC. Go to the following link:

- Select Service limit increase
- Limit type: VPC
- Region: <your region>
- Limit:  Provides dropdown for both
      - VPN connections per Region
       - VPN connections per VPC
- Fill in Use case description and contact info

Hope this helps!
