We have a DMZ and LAN in our office that are connected to the outside with the following setup:
+------+ | |------> LAN (normal office router) |Modem | | |------> DMZ (a single machine) +------+
Our internet account is with Comcast and we have 5 status IPs, one of which points to the single machine in the DMZ.
ssh connections initiated ANYWHERE EXCEPT the office LAN are really fast. However, from the LAN, there is about a 5 second delay. WTF??
The DMZ machine is debian 5.
wget to the DMZ has no lag.
When executing the following, everything up to
HERE IS WHERE THE LAG IS INCURRED executes immediately.
