Connections problems to specefic IP addresses

Hi,

I am pretty new to this, so please be patience with me :-)

I have a problem with one of my setup in our Hong Kong office..
Let me describe my setup first

Internet - HP3500 - HP2626

From my HP3500 i can ping all known addresses

From the HP2626 not all ip addresses are available

Ping from HP3500
HK-WAN-HP3500# ping 77.68.129.64
77.68.129.64 is alive, time = 359 ms
HK-WAN-HP3500# ping 8.8.8.8
8.8.8.8 is alive, time = 26 ms
HK-WAN-HP3500#

Ping from HP2626
TC-HK DMZ SW# ping 77.68.129.64
77.68.129.64 is alive, time = 350 ms
TC-HK DMZ SW# ping 8.8.8.8
Target did not respond.
TC-HK DMZ SW#

Please see the attached file for detailed setup..

Here is a detailed description of the configuration of the devices..

Hope this make sense for you..
The big problem in this case is that I cant access my isp dns from the HP2626

Looking forward to hear from you all..

Re: Connections problems to specefic IP addresses

in the 2626 did you configure ip default gateway or static default route ?

Also try to trace the route from a PC and check.
