Since several days I have a working tunnel with an XP Machine (1). I use this tunnel to connect to newszilla6.xs4all.nl (usenet junkie client) Another XP machine (2)on the same network will not work. On both machines I have IPV6 installed. Connections: internet --- router WRT54G --- XP (1) 192.168.0.1 --- XP (2) 192.168.0.x I use following commands to activate the tunnel after each reboot and this works for machine (1). When I turn off machine (1) and turn on machine (2) the same commands (except for the IP-address) will not work. ipv6 ifcr v6v4 192.168.0.1 213.204.193.2 ipv6 ifc <interfacenummer> forwards ipv6 adu <interfacenummer>/2001:960:2:3bb::2 ipv6 rtu ::/0 <interfacenummer>/2001:960:2:3bb::1 Above commands will give me a working tunnel on (1), but on machine (2) it will not work. Results on machine 1 : Bezig met pingen van newszilla6.xs4all.nl [2001:888:0:4::119] vanaf 2001:960:2:3bb::2 met 32 bytes aan gegevens: Antwoord van 2001:888:0:4::119: bytes=32 tijd=109ms Antwoord van 2001:888:0:4::119: bytes=32 tijd=75ms Antwoord van 2001:888:0:4::119: bytes=32 tijd=134ms Antwoord van 2001:888:0:4::119: bytes=32 tijd=260ms Ping-statistieken voor 2001:888:0:4::119: Pakketten: verzonden = 4, ontvangen = 4, verloren = 0 (0% verlies), Retourtijd in ms circa: Minimum = 75ms, maximum = 260ms, gemiddelde = 144ms Results on machine 2 : pinging is possible but when I try to contact the newszilla6.xs4all.nl server by using 127.0.0.1 as hostname in usenet junkie it does not work. Can anyone give me a hint how to solve this problem ?
