Help with IPv6 router config...

[Juan Luis Baptiste]

Hi,

I  think finally I understanded how click elements work, so I wroted an ipv6
router configuration that
uses
two interfaces, based in one of the configuration files that comes with click.

The router works fine, but when I try to enter a to a web page in one of the
machines in the other network

it takes arround one minute or more before the page is displayed.

ping6 and ssh works fine.

The network setup is as follows:

3ffe:1ce1:2:0:200::2
               |
               |
3ffe:1ce1:2:0:200::1
3ffe:1ce1:2::2
               |
               |
3ffe:1ce1:2::1

Here is my configuration file:

extern_nda::IP6NDAdvertiser(3ffe:1ce1:2:0:200::1/128	00:50:8b:65:2c:23,
                            fe80::250:8bff:fe65:2c23/128	00:50:8b:65:2c:23);
extern_nds:: IP6NDSolicitor(fe80::250:8bff:fe65:2c23, 00:50:8b:65:2c:23);

intern_nda::IP6NDAdvertiser(3ffe:1ce1:2::2/128	00:60:97:C0:D4:74,
