Hi, I am trying to get aiccu to work on a DD-WRT router. The tunnel gets setup but there is no traffic possible through the tunnel. Tunnel Information for T23783: POP Id : bebru01 IPv6 Local : 2001:6f8:202:3fc::2/64 IPv6 Remote : 2001:6f8:202:3fc::1/64 Tunnel Type : ayiya Adminstate : enabled Userstate : enabled ####### ####### AICCU Quick Connectivity Test ####### ####### [1/8] Ping the IPv4 Local/Your Outer Endpoint (84.194.241.209) ### This should return so called 'echo replies' ### If it doesn't then check your firewall settings ### Your local endpoint should always be pingable ### It could also indicate problems with your IPv4 stack PING 84.194.241.209 (84.194.241.209): 56 data bytes 64 bytes from 84.194.241.209: seq=0 ttl=64 time=0.437 ms 64 bytes from 84.194.241.209: seq=1 ttl=64 time=0.331 ms 64 bytes from 84.194.241.209: seq=2 ttl=64 time=0.330 ms --- 84.194.241.209 ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max = 0.330/0.366/0.437 ms ###### Did this work?

[Y/n] n I checked the firewall but it isn't dropping any packets. Furthermore, a tcpdump on my external interface while pinging Remote/PoP Inner Tunnel Endpoint shows the following: # ping6 2001:6f8:202:3fc::1 PING 2001:6f8:202:3fc::1 (2001:6f8:202:3fc::1): 56 data bytes # tcpdump -n -i vlan2 host 212.100.184.146 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on vlan2, link-type EN10MB (Ethernet), capture size 68 bytes 15:28:09.554290 IP 84.194.241.209.32780 > 212.100.184.146.5072: UDP, length 152 15:28:10.564278 IP 84.194.241.209.32780 > 212.100.184.146.5072: UDP, length 152 15:28:11.574277 IP 84.194.241.209.32780 > 212.100.184.146.5072: UDP, length 152 15:28:12.584278 IP 84.194.241.209.32780 > 212.100.184.146.5072: UDP, length 152 When I ping6 2001:6f8:202:3fc::1 (my local inner tunnel endpoint) from another ipv6 host under my control, I see the following on my tcpdump (outgoing ping6 stopped): tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on vlan2, link-type EN10MB (Ethernet), capture size 68 bytes 15:30:59.808707 IP 212.100.184.146.5072 > 84.194.241.209.32780: UDP, length 148 15:30:59.809650 IP 84.194.241.209.32780 > 212.100.184.146.5072: UDP, length 152 15:31:00.822851 IP 212.100.184.146.5072 > 84.194.241.209.32780: UDP, length 148 15:31:00.823690 IP 84.194.241.209.32780 > 212.100.184.146.5072: UDP, length 152 15:31:01.821846 IP 212.100.184.146.5072 > 84.194.241.209.32780: UDP, length 148 15:31:01.822693 IP 84.194.241.209.32780 > 212.100.184.146.5072: UDP, length 152 So it seems that my outgoing ipv6 traffic is rejected somewhere along the path. Does anyone has an idea what might be going on here? Thanks, Kind regards, Tom
