Block port 80 but allow IM
I'm trying to block web access for some LAN IP but I want to allow MSN messenger to continue to work. I have created a firewall rule in LAN tab (please see picture attached) but it also blocks msn messenger.
any help will be appreciated.

Do you have added allow rule for MSN Messenger TCP port (1863)?

According to http://portforward.com/cports.htm
1863, 6891-6900, 6901 1863, 5190, 6901
I believe MSN uses 1863 for its main connection, the other ports listed maybe for voice clips, webcam, sharing files. Depending on your MSN client as well i have heard of it using 443 (SSL).
** Remember to set your allows at the TOP and the block * at the bottom, rules are processed from the top down, and if you do block all then allow 1863 it will ignore it.
No I only blocked port 80 and assumed that all other ports would work as normal.
Thanx guys I will try allowing those ports to see if it will work and I will post back.

yeah….this right...the standart port of windows live messenger is important.
i have block some others: icq , msn , skype
with firewall you can block icq and msn.
with make firewall rules for your specific programs and so the port 1863 are not allowed ;)
when some messenger like skype use also port 80 or 443 (http, https) then you need a paketfilter like snort - to analyse one layer deeper, in the packages -
to identificate skype login or file-transfer or simething like that^^
it works great for me!
No ChatTools :)
it works when i allow all the listed ports there, not just one.
