I have a FreeBSD 7.0 system and I recently enabled ipv6. I configured Apache, Exim and Dovecot to use newly added ipv6 address. I can ping the ipv6 address but when I try to browse or ssh to the system, it doesn't work. I tried tcpdump and I can see SYN packet coming to the server but the server is not sending back ACK. I think the problem is with TCP stack but have no clue what might be wrong.
Any help will be highly appreciated.
