Connectivity between multiple networks

[Sumitsrjhs]

Hi Freinds

I have setup Openswan server on AWS ec2. I have one VPN configured from AWS to GCP and another Openswan to my on-prem site.
I can ping from GCP to Openswan ec2, similar from my on-prem site to Openswan Ec2 IP.
Also, I can ping From My On-prem Site to GCP IP as we, but can't ping from GCP to My On-Prem IPs.
There is only one NIC on my Openswan EC2 i.e. ens5.
I also configured MASQUERADE:
iptables -t nat -A POSTROUTING -o ens5 -j MASQUERADE
I have also enabled IP forwarding.

Please suggest

openswan has been abandoned years ago. Use libreswan or strongswan instead.PaulSent using a virtual keyboard on a phoneOn Aug 10, 2024, at 12:28, Sumitsrjhs ***@***.***> wrote: Hi Freinds I have setup Openswan server on AWS ec2.

HI Letoams

Yes, I upgraded it to strongswan already.
Can you please suggest a solution to my query?

Thanks
