Hi, i´m having this weird issue. i have ipv6 on router with a /64 PD (i tried forcing for more but was left with a 64). Clients on a subnet with that delegated prefix can get valid ip and have funcional ipv6 connectivity. but when i try to ping an internet ipv6 address from the router i get the icmp on the interface out but never get a reply, will try to explain:
root@c7:/var# ip -6 a list eth0.10
24: eth0.10@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP100> mtu 1500 state UP qlen 1000
inet6 2000:abcd:abcd:1010:52c7:bfff:fef9:34df/64 scope global dynamic noprefixroute
valid_lft 2591997sec preferred_lft 604797sec
inet6 2000:abcd:abcd:1020:52c7:bfff:fef9:34df/64 scope global dynamic noprefixroute
valid_lft 2591997sec preferred_lft 604797sec
inet6 2000:abcd:abcd:1000:52c7:bfff:fef9:34df/64 scope global dynamic noprefixroute
valid_lft 2591785sec preferred_lft 604585sec
inet6 2000:abcd:abcd:1000:ecd4:17b:c77:3d34/128 scope global dynamic noprefixroute
valid_lft 80561sec preferred_lft 66161sec
inet6 fe80::52c7:bfff:fef9:34df/64 scope link
valid_lft forever preferred_lft forever
The icmp packet when i do a ping6 www.google.com for example goes on OUT IF with source 2000:abcd:abcd:1020:52c7:bfff:fef9:34df, no returns. But if i request to use the /128 global one (2000:abcd:abcd:1000:ecd4:17b:c77:3d34/128) by passing -I and that ip to the ping command it works ok. Also if i manually delete the /64 global ip (all 3 of them) it momentarily works without the argument, so i was wondering.
Is there any dhcpv6c argument i can pass on my wan6 interface to request only the /128 and the PD so i can get a funcional stack on the router? maybe any other suggestion?
I need that working so i can properly NAT6 the other subnets i currently use.
Thank you guys in advance.
