I’ve been playing around with IPv6 port filtering and I’ve found two things:
1st. Allowing a specific destination IP doesn’t work. If I allow a range, even if the netmask is 127. The firewall allows the incoming connection. But if the destination IP is set to single, the rule does not work.
Example of a rule that doesn’t work for me:
- Inbound/Enable/Traffic policy: Yes
- Protocol: TCP
- Source IP Address: All
- Destination IP addres: Single
- Source port range: 1 65535
- Destination port range: 3000:3000
Also the netmask is shown as /0 instead of 128 in single destination IP mode. In range mode there is a similar UI error, where the netmask is shown as “/0”
2nd. Protocol “all” does not work with all protocols. Setting “all” as protocol in the rule allows ICMPv6 but not TCP or UDP.
Can anybody else confirm this?
