Infrastructure Software

Hi all,

I have recently installed Solaris 10 11/06 x86 and it appears to be running interference with my broadband

router, I'm quite new to Solaris and Unix as a whole so am lost as to how to track and fix this problem

(if it is fixable).


Please help, Any assistance much appreciated.


Kenny.

PC1
Model: HP Workstation xw6000 dual Xeon
Memory: 4GB
OS: Solaris 10 11/06 x86 [Full Install + security and recommended patches]
NIC: Intel PRO/1000 MT Desktop Adapter

PC2
Model: [Custom] Asus NCCH-DL Dual Xeon
Memory: 2GB
OS: Windows XP Pro 2002 SP2 [all security and critical patches installed]
NIC: Intel PRO/1000 MT Dual Port Server Adapter

Broadband Router
Model: Vigor2600V series annex A, Firmware: v2.5.8.3_UK

Problem:
Solaris interferes with the router stopping all internet connections

Observations:
The fault seems to be caused by the interactions of the Solaris TCP/IP Stack and the Vigor Router.
Same fault when PC2 had Windows 2003 Server R2 installed.
Same fault when PC2 had Solaris 10 11/06 installed.
The LAN appears unaffected, can SSH to PC1 from PC2 without any side effects.
Every so often can connect to the internet from PC2 for some minutes before connection is lost.
When connection is lost it remains down for some time, ADSL remains online.
When connection is lost no part of the WAN is communicable, no ping, etc...
When disconnecting PC1 from router, within 30-45 seconds everything returns to normal, I do not have to reboot router.


Notes:
Both PC's have IP addresses set statically, not via DHCP.
The DNS address for both PC's references the router.
Currently I have to physically disconnect the network cable to PC1 or shutdown the Solaris OS in order

to use the internet from PC2.

Even with all this I'm loving Solaris but will have to return to W2K3 Server if this issue cannot be

resolved as it is unworkable, please help.
