Hi, I'm having some troubles with the NAT-PT implementation. I'm running FreeBSD 4.5 and I have installed the Kame SNAP release kame-20021104-freebsd45-snap.tgz. With this, I have configured a NAT-PT router. Then I have a DNS IPv6-native (toghether with anorther machines which have no relevance hear).
I have no problems when I do ping6 to any IPv4 machine (using the NAT-PT prefix), neither to any IPv6 machine if I write down the address, not its name. When I take a look at the tcpdump, it shows a "bad UDP cheksum", so even if our DNS gets the answer for a name (the forwarder sends to it) it discards the packet. I have a similar situation with TCP. I've tried telnet to the HTTP port and I get the web page with "bad TCP cheksum", so it is discarded. But the strange thing is that I have no problem when I do ping6 6to4.kfu.com. I get the DNS answer and the ping6 works!. Another thing I tried was dig @my_forwarder some_ipv4_machine_name A and it works, I get the answer. And when I do the same query for a machine which has both A and AAAA records, sometimes it works, but mostly doesn�t. So I'm a bit confused, because at first sight it looked like a transport layer problem with the cheksum computation, but then I have no problem with some particular address!. Sorry for the mail length, I tried to be clear with the problem. I'd appreciate if someone could help me. Thanks, Nico. --------------------------------------------------------------------- The IPv6 Users Mailing List Unsubscribe by sending "unsubscribe users" to [EMAIL PROTECTED]
