I have a new 8901 that I am having difficulty configuring. The Web

interface is quite different from my old model and the firewall page

in particular.

I want to close ftp inbound on 21, telnet both ways on 23, and port 80

inbound. Why these are open by default I don't know. I see that I

can close ALL ports inbound with the SPI option in the firewall

dialog, but that option also disables all ports intentionally

forwarded for P2P, so it isn't an option for me.

I suspect that I can do this in Access Mgt/Filters, but I have been

unable to figure out the documentation after considerable study. Can

someone with experience on this model help me?

I don't own this particular model (I have an older TD-8810), so I'm making a guess here. The settings you need to configure should be under Access Management >> ACL. Configure the Application and Interface options to suit your needs.

Thanks for that, I'll take a look
