Is the above possible?
My folks have finally got broadband but due to complications they're with an ISP that won't assign them a static IP. They've got an old Redhat gateway I built about 5 years ago that originally protected their wireless and wired computers, did squid, named etc. and also their dial up. Now that they have a proper connection I'm building them a new gentoo box and would like to do OpenSWAN between them and me.
Will I be about to do a net to net tunnel even though their public IP is likely to change? I appreciate that computers in my net won't be able to see computers in their net until their concentrator has authenticated with mine but is it even possible? |

Just to follow on in case someone else finds this useful. Found good starter was the road-warrior configuration at the OpenSWAN wiki. Just to refresh you, this is what things used to look like:
This was the code I was testing with for the above problem. In original testing I'd assigned their new box a static address in my public address space, and all was well:
Code: |
#
# Tunnel details from my_house to my_folks
#
conn my_house-my_folks
left=MY_GATEWAY_IP
leftsubnet=10.6.0.0/16
leftsourceip=10.6.0.1
leftid=@my_gateway.mydomain.com
leftrsasigkey=blabla
right=THEIR_GATEWAY_IP
rightsubnet=10.7.0.0/16
rightsourceip=10.7.0.1
rightid=@their_gateway.mydomain.com
rightrsasigkey=foofoo
authby=rsasig
auto=add
compress=yes
|
And it works, and everyone is happy, were it not for their ISP who won't let them have a static IP. Testing so far says that this will work but I'm not going to know till I get there at Christmas and I'm behind their router. Anyway, I'm trying this now. This is the tweaked road-warrior configuration but with the subset definitions. I looked all over and didn't find an example of this out right so I hope it's useful.
On MY_GATEWAY:
Code: |
conn my_house-my_folks
left=MY_GATEWAY_IP
leftsubnet=10.6.0.0/16
leftsourceip=10.6.0.1
leftid=@homer.chuci.org
leftrsasigkey=blabla
right=%any
rightsubnet=10.7.0.0/16
rightsourceip=10.7.0.1
rightid=@their_gateway.mydomain.com
rightrsasigkey=foofoo
authby=rsasig
auto=add
compress=yes
|
On THEIR_GATEWAY:
Code: |
conn my_house-my_folks
left=MY_GATEWAY_IP
leftsubnet=10.6.0.0/16
leftsourceip=10.6.0.1
leftid=@my_gateway.mydomain.com
leftrsasigkey=blabla
right=%defaultroute
rightsubnet=10.7.0.0/16
rightsourceip=10.7.0.1
rightid=@their_gateway.mydomain.com
rightrsasigkey=foofoo
authby=rsasig
auto=add
compress=yes
