Can view website but can't ping server
So I have a Debian server back home behind a Linksys router with port forwarding set to 21, 22, 23, 25, and 80. The FQDN is www.bublades.com
Put in in your web browser and take a look. The website comes up just fine. You can also ssh or sftp to it.
The problem is that I want to set it up with mailman to be able to send mail to all the members of the organization. So I installed sendmail with apt, but then I realized that I cannot ping the server or telnet to it.
Does anyone have any idea what is going on?

They very well might have ICMP Echo disabled, to prevent attempted Ping of Deaths, and similar attacks. Also, many people close their telnet port, as it's not commonly used anymore.
