Hi, I'm currently trying to configure NAT-PT to allow our IPv6-only clients to access IPv4 hosts. We've bought an 2811 for this task (among others) and I tried following
http://www.cisco.com/en/US/docs/ios/12_2t/ipv6/SA_natpt_ps6350_TSD_Products_Configuration_Guide_Chapter.html#wp1073195 http://www.civil-tongue.net/clusterf/wiki/Cisco IOS NAT-PT Configuration but I'm getting the same error message the guys at NANOG got. Feb 25 13:39:40.495: IPv6 NAT:v4tov6 entry not found The relevant config sections should be the following --- interface FastEthernet0/0 ip address 129.187.18.250 255.255.255.0 ipv6 address 2001:4CA0:0:FF00::FFFF/64 ipv6 nd suppress-ra ipv6 nat ipv6 route ::/0 FastEthernet0/0 2001:4CA0:0:FF00::1 ipv6 nat v6v4 source list LRZ interface FastEthernet0/0 overload ipv6 nat prefix 2001:4CA0:0:FF03::/96 ipv6 access-list LRZ permit ipv6 2001:4ca0::/32 any --- I tried adding ipv6 nat v4v6 source 129.187.18.250 2001:4CA0:0:FF00::FFFF and ipv6 nat prefix 2001:4CA0:0:FF03::/96 v4-mapped LRZ but this didn't change the behaviour at all. I've tried 12.4(18) and 12.4(15)T3 (both ADVANCED IP SERVICES), no difference. 12.4(15)T3 spits out more debugging information though: *Feb 25 13:58:59.527: IPv6 NAT:v4tov6 entry not found *Feb 25 13:58:59.959: IPv6 NAT: ipv6nat_find_entry_v4tov6: ref_count = 1, usecount = 0, flags = 2, rt_flags = 0, more_flags = 4 *Feb 25 13:58:59.963: IPv6 NAT: tcp src (2001:4CA0:0:F000:211:43FF:FE7E:3A76) -> (129.187.18.250), dst (2001:4CA0:0:FF03::53AA:645) -> (83.170.6.69) *Feb 25 13:59:05.959: IPv6 NAT: ipv6nat_find_entry_v4tov6: ref_count = 1, usecount = 0, flags = 2, rt_flags = 0, more_flags = 4 Anyone having an idea?
