Shields-up shows telnet (23) is open by default, so I added an inbound filter rule but telnet still says it is open.

There's no allow/block setting on the inbound rules

If I log an inbound rule I seem to get the return packets from outbound rules. (So it's not stateful?)

Firewall is enabled on WAN interface. Firmware is: 2.32d.dm12

I have some virtual servers set up. These seem to work.

Am I missing something?

OK I have it. It seems that these ports are always open for router access. Best have a good password then! (Any way to close them?)

And default is block so rules have effect of allowing.

Sorry this was posted while I was learning ... I have replaced this by a separate post now I understand a bit more.
