I tried RTFM and much Googling, but we are still stuck.
Both machines report established SAD, however, the Monowall (Soekris,
1.2b7) does not show a route for the remote subnet and there is no gif
interface (on the Monowall) showing up for the tunnel (does Monowall not
use a gif interface?).
Are we missing something on the Monowall config?
(remote-gateway and pre-shared-key have been sanitized)
Also, is there any way to use a x509 certificate for Phase 1 identification?
BTW, been using Monowall for almost a year as a general firewall at home
with virtually no issues - very stable!
