I'm working on a site to site connection from my VPC to my on prem OPNsense
VPN.


Cloudstack Version 4.19.0
OPNSense Version 23.4.2

I have two P2 selectors setup in OPNsense and i've got a VPN customer
gateway setup with two subnets (  192.168.251.0/26,172.16.192.0/20 ) in
Cloudstack.

The issue im running into is, only the first address in my  VPN customer
gateway gets added to the SAD. So, In the above example, since
192.168.251.0/26 is first I can pass traffic to and from the VPC to that
subnet on prem. However, 172.16.192.0/20 is not added.

I checked the logs on my VPC VR and found the following.


Feb 18 06:11:56 r-407-VM charon: 07[CFG] unable to install policy
172.16.192.0/20 === 10.241.0.0/16 in for reqid 3, the same policy for reqid
5 exists
Feb 18 06:11:56 r-407-VM charon: 07[CFG] unable to install policy
172.16.192.0/20 === 10.241.0.0/16 fwd for reqid 3, the same policy for
reqid 5 exists
Feb 18 06:11:56 r-407-VM charon: 07[CFG] unable to install policy
10.241.0.0/16 === 172.16.192.0/20 out for reqid 3, the same policy for
reqid 5 exists


Wondering if i'm just formatting my  VPN customer gateway CIDRs wrong?


Thanks!
Wally
