Hello users,
I'm new to the world of linux VPN, however, i'm trying to setup a vpn
site-to-site connection using the openswan 2.3.0-1 (installed the rpm
version), although i have read the configuration howto, and nearly 5
examples, i can not figure out how to configure my ipsec.conf because
of the network setup i have. I would really appriciate any help in
configuring the ipsec file. i'm using two diffrent ADSL account with
ADSL router with NAT, one of which is a dynamic ip, the subnets are : and , while the linux boxes (fedora core
3) are and, the router internal addresses
are and i'm using RSA sig for
authentication , i have reteived the keys using showhostkey. I would
really apriciate if someone could send me a step-by-step setup for
such case. thanks
