I'm trying to setup a multiple site-tosite connectivity with Openswan as
central point. I'm trying to connect 2 AWS regions and 1 Azure region. I'm
using AWS VPN Gateway in one of AWS regions (AWS-US), VPN Gateway in Azure,
and Openswan in the main AWS region (AWS-EU). I can successfully connect
between AWS regions and main AWS and Azure. So currently I have:
But I'd like to achieve also connectivity between AWS-US and Azure via
>From the clouds configuration side, all Routing is propagated properly.
CIDR block of networks:
So no cidr overlapping.
I tried various configuratoins but always ended up with one region not able
to communicate with another.
My current setup (OS:Amazon Linux, openswan 18.104.22.168):
with this setup I have following connectivity working:
So i'm lacking connectivity between AWS-EU and AWS-US despite tunnel being
up and other cross connectivity working.
ipsec look shows me all the routes I expected to see
Iptables on Openswan instance has no rules applied, traffic on security
groups is allowed,
Any ideas what might be the issue or how to debug?
Thank you in advance.
