Weird(?) HTB3 setup
Hi,
I want to be able to specify actions for different classes of
traffic in any of these four ways, and I''d like to use only
HTB if possible:
1. No guranteed rate, No ceil
2. Guaranteed rate, No ceil
3. No guranteed rate, Ceil specified
4. Guaranteed rate, Ceil specified
For types 2, 3 and 4 there can be several classes of each, with
different rates and ceilings.
4 is ofcourse easy.

${EXTERNAL_IP}
Forwarding was enabled _after_ installing the iptablesrules.
I think that an unusal combination of flags causes that problem a...

TCP/IP Port Relay
What is the best way to temporarily setup a port relay. I'm trying to
diagnose a problem with Cisco's latest VPN client and need to determine
if the problem is port number related.
e.g. VPN client---------23-(Linux box to relay port)-------xx-(Telnet
server)
(Keep in mind this is temporary and for debugging purposes)
Thanks,
