::ffff:192.168.0.xx, destination unreachable

Hello,
on my shiny little box from inception hosting (the one with 64mb of ram, 1 private ipv4 natted and 5x ipv6) I want to telnet my lan ip (192.168.0.xx) with the ipv6 mapping.
If I do:

telnet ::ffff:192.168.0.xx PORT

it works, but if I specify an address:

telnet -b BOX-IPv6-Address ::ffff:192.168.0.xx PORT

I obtain "destination unreachable".

Someone can give me a clue?

Thanks

    telnet :s ooh eerr

    Not exactly sure what you are trying to achieve, you have set up a telnet server (For some reason) and then made it listen on one of the pre allocated port numbers and now you cant reach it?

    Or you have some other service running on xxxx port and you are using telnet to test connectivity?

    This.

    I'm trying to track why my irc bouncer (ipv6, that make only ipv6 connections) get destination unreachable when I try to connect to a local service with the ipv4 mapping.

    As I said the problem only appear when I specify a source IPv6 address; I suppose that I miss some routing rules, but I didn't understood which one.

    You want to use an IPv4 address with the IPv6 protocol.

  • @hostingwizard_net said: You want to use an IPv4 address with the IPv6 protocol.

    That's the meaning of ::ffff:0:0/96, AFAIK. ;)

  • Yes, except I think that even though it's IPv4 mapped over IPv6, you have to use colons rather than periods:

    ::ffff:192:168:0:xx PORT

    No. You CAN use colons only if you convert the IPv4 in hex (for example for ::ffff:192.168.0.1 can be converted in ::ffff:c0a8:0001); but is not mandatory.
