It is given in the freeswan how-to. The current freeswan contrib at contribs.org will allow the use of IP address or dns name (dynamic or otherwise) to refer to the end points.

And I would answer in short "Follow the freeswan howto at contribs.org" :)

And I'd Ask "Ok, I put 'www.mydynamicdomain.com' in the 'Remote Router's External IP Address:' , but WTF do I put in 'Remote Router's External Gateway IP' "??? ;-)

Although my freeswan and howto (dmc-mitel-freeswan-1.97-3sme55.noarch.rpm)come from contrib.org, there is not a word in the howto about dynamic DNSes...

Hi Phillipe,

I skipped SME 5.5 and anything to to with it altogether, so I am unfamiliar with your version of the freeswan howto.

The Freeswan Howto I use is the one from Shad Lords. While the freeswan how-to does not explicitly mention dynamic IP addresses, you will find that it mentions that you can use either a dns (or hostname) or an IP address for the remote address which means, you can use dynamic IPs (if you update your IP with a dynamic DNS provider) with that contrib.

Shad's howto does not require you to enter the remote gateway address either.
