Change of IP Address & Gateway on XPS M1710 fails to connect to Interenet

Question

My XPS M1710 with XP SP2 has worked faultlessly for 12 months over our wireless network. I want to add a Yoggie Gatekeeper SOHO firewall onto the router.  The Yoggie becomes the gateway and also becomes the DHCP server, instead of the router.  The other PCs are ok with this and work properly.   However the M1710 although renewing the network addresses refuses to connect to the internet and cannot ping any other device on the network - although they can ping it!  Ipconfig /all, ARP, and Netstat all give correct results. I can't think where else to look, but it is obviously a problem with the XPS.  The original IPA/Gateway are in the 192.168.2.x range, and the new ones are 192.168.4.x.  Any help would be appreciated.

Post the results of an ipconfig /all from a machine that can connect and also the trouble one.

Here are the 2 IPconfig /all outputs - as you can see, the only differences are the unique addresses and the hardware details!   This is the working unit :-   Windows IP Configuration           Host Name . . . . . . . . . . . . : dta-base         Primary Dns Suffix  . . . . . . . :         Node Type . . . . . . . . . . . . : Unknown         IP Routing Enabled. . . . . . . . : No         WINS Proxy Enabled. . . . . . . . : No         DNS Suffix Search List. . . . . . : localdomain   Ethernet adapter Local Area Connection 4:           Media State . . . . . . . . . . . : Media disconnected         Description . . . . . . . . . . . : TE100-PCBUSR 32-Bit Cardbus PC Card #2         Physical Address. . . . . . . . . : 00-0E-2E-29-7E-FD   Ethernet adapter Wireless Network Connection:           Connection-specific DNS Suffix  . : localdomain         Description . . . . . . . . . . . : Belkin 802.11g Wireless Card         Physical Address. . . . . . . . . : 00-11-50-8F-53-50         Dhcp Enabled. . . . . . . . . . . : Yes         Autoconfiguration Enabled . . . . : Yes         IP Address. . . . . . . . . . . . : 192.168.4.200         Subnet Mask . . . . . . . . . . . : 255.255.255.0         Default Gateway . . . . . . . . . : 192.168.4.1         DHCP Server . . . . . . . . . . . : 192.168.4.1         DNS Servers . . . . . . . . . . . : 192.168.4.1         Lease Obtained. . . . . . . . . . : 29 August 2007 11:59:13         Lease Expires . . . . . . . . . . : 29 August 2007 12:09:13   And this the failing unit :-   Windows IP Configuration           Host Name . . . . . . . . . . . . : COSMOS         Primary Dns Suffix  . . . . . . . :         Node Type . . . . . . . . . . . . : Unknown         IP Routing Enabled. . . . . . . . : No         WINS Proxy Enabled. . . . . . . . : No         DNS Suffix Search List. . . . . . : localdomain   Ethernet adapter Wireless Network Connection:           Connection-specific DNS Suffix  . : localdomain         Description . . . . . . . . . . . : Intel(R) PRO/Wireless 3945ABG Network Connection         Physical Address. . . . . . . . . : 00-13-02-BC-98-A8         Dhcp Enabled. . . . . . . . . . . : Yes         Autoconfiguration Enabled . . . . : Yes         IP Address. . . . . . . . . . . . : 192.168.4.199         Subnet Mask . . . . . . . . . . . : 255.255.255.0         Default Gateway . . . . . . . . . : 192.168.4.1         DHCP Server . . . . . . . . . . . : 192.168.4.1         DNS Servers . . . . . . . . . . . : 192.168.4.1         Lease Obtained. . . . . . . . . . : 29 August 2007 12:06:29         Lease Expires . . . . . . . . . . : 29 August 2007 12:16:29   Ethernet adapter Local Area Connection:           Media State . . . . . . . . . . . : Media disconnected         Description . . . . . . . . . . . : Broadcom NetXtreme 57xx Gigabit Controller         Physical Address. . . . . . . . . : 00-15-C5-43-72-03   Thanks,   Jeanette.

Everything looks good except for the lease time period.  Why are these set for 10 minutes?  Normally a SOHO router will give IP addresses for a 24 hour time period.

JEANETTE ATTWOO · Answer

The lease time at this point is not from the router which gives a 1 year period, but from the Yoggie over which I have no control.  I have contacted Yoggie support for an answer to your question and will post the information when I have it.   For completeness sake I include a copy of ipconfig for the M1710 in it's working state (i.e. without the Yoggie connected) :-   Windows IP Configuration           Host Name . . . . . . . . . . . . : COSMOS         Primary Dns Suffix  . . . . . . . :         Node Type . . . . . . . . . . . . : Unknown         IP Routing Enabled. . . . . . . . : No         WINS Proxy Enabled. . . . . . . . : No         DNS Suffix Search List. . . . . . : jdhome   Ethernet adapter Local Area Connection:           Media State . . . . . . . . . . . : Media disconnected         Description . . . . . . . . . . . : Broadcom NetXtreme 57xx Gigabit Controller         Physical Address. . . . . . . . . : 00-15-C5-43-72-03   Ethernet adapter Wireless Network Connection:           Connection-specific DNS Suffix  . : jdhome         Description . . . . . . . . . . . : Intel(R) PRO/Wireless 3945ABG Network Connection         Physical Address. . . . . . . . . : 00-13-02-BC-98-A8         Dhcp Enabled. . . . . . . . . . . : Yes         Autoconfiguration Enabled . . . . : Yes         IP Address. . . . . . . . . . . . : 192.168.2.5         Subnet Mask . . . . . . . . . . . : 255.255.255.0         Default Gateway . . . . . . . . . : 192.168.2.1         DHCP Server . . . . . . . . . . . : 192.168.2.1         DNS Servers . . . . . . . . . . . : 192.168.2.1         Lease Obtained. . . . . . . . . . : 29 August 2007 20:03:30         Lease Expires . . . . . . . . . . : 28 August 2008 20:03:30   Thanks,   Jeanette.

This looks okay wxceptr I think you typed the Lease Obtained and Expires infor in backwards.   Why do you feel it is necessary to have this other gateway involved?  My guess is that you will need to disable the DHCP server on the present router in order to use that other device.

JEANETTE ATTWOO · Answer

Have a look at www.Yoggie.com - it  acts as a firewall and web security device.  With up to 5 pcs to secure it works out a lot cheaper than multiple Norton licences, and works for me except for this Dell XPS.  It provides the DHCP service, and the DHCP server is switched off in the router, and as I said,  the other units connect to the internet without a problem when the Yoggie is in the loop.  As it is an ALL or Nothing case, I need to get the M1710 running with the Yoggie.  Regards the typing of the Lease info - they were cut and pasted, but they refer to different years, with the expiry being 2008.

JEANETTE ATTWOO · Answer

The first 2 IPconfigs in the earlier posting are /all from a working unit and the m1710 both with the Yoggie in place.  They are the ones with the 10 min lease times, and the M1710 being the one with the Intel 3945 wireless hardware.

jmwills · Answer

Can I see an ipconfig /all with the Yoggie in place?

JEANETTE ATTWOO · Answer

I have had a reply about lease times from ythe Yoggie support desk - here it is :

I have asked our engineers, and our DHCP is in fact configured to give a 10 minutes lease time.
It a reasonable lease time which provides easier DHCP management for our products and helps keep the IP database small.
This factor should not have any influence on the connectivity.
If we'll recognize a problem with this issue in the future, it will added to the features of our products.
