Greetings,
I've just deployed UTM9 to replace ASG 8. Because our set of rules and definitions was aging (it goes back to v4) I've decided to redo everything from scratch.
We're using Link aggregation of two gig network cards with vlans. So far everything is working as plan ... But we have issues with IPv6
Our DMZ and Public zone have public IP addresses (4 and 6 in dual stack)
Our internal zone has RFC 1918 and IPv6 in dual stack
SSH from internal to DMZ is impossible in IPv6, but http, https, smtp, pop, imap, dns ... are going through with no problem.
I've made a rule that allow the SSH traffic with logging. The traffic is not blocked by the firewall, it just dosen't get to its destination !
If I use the IPv4 address, I get to connect all the servers in the DMZ.
Can someone give me a hint on where to start looking ? I'm a bit lost here
Thanks
