Step Nine: Testing MASQ functionality without DNS Now try TELNETing to a remote IP address (i.e. telnet
152.2.210.81 ( this is technically the DNS name "metalab.unc.edu").
It might take a few seconds to get a login prompt since this is a VERY busy
server. Did you get a login prompt like shown below? If so, it means that
TCP Masquerading is running OK. If not, try TELNETing to some other hosts you
think will support TELNET like 198.182.196.55 (www.linux.org). If this still
doesn't work, make sure you are using the simple rc.firewall-* ruleset for this
test. An example of this output might look like (hit Control-D to exit out of
the TELNET):
--------------------------------
masq-client# telnet 152.2.210.80
Trying 152.2.210.80...
Connected to 152.2.210.80.
