My telepathic abilities are getting rusty these days, but if guessing |
| 39 |
is allowed I think that the OP wanted to set up gentoo so that he |
| 40 |
could access the Zyxel router's firewall and modify its rules, from |
| 41 |
the Gentoo desktop. Either that, or he's thinking of building an |
| 42 |
embedded image for Zyxel?! |
| 43 |
|
| 44 |
More info would no doubt help. If not anything else, tell us what |
| 45 |
Zyxel can and cannot do - if it allows ssh access to its OS, then you |
| 46 |
may be able to set up firewall builder on the Gentoo box and use that |
| 47 |
to access/setup the Zyxel firewall. If you are running OpenWRT (not |
| 48 |
sure if this would run on Zyxel, but just don't stop me guessing now) |
| 49 |
you should be able to cook something so that firewall builder could |
| 50 |
hook into it. |

Best of luck, |
