Network Problem Solved but.....

[Imran .]

Okay. Problem is solved. I looked at router's routing table and i am 
wondering why it was like this?
First let me tell u my network settings:
IP address of Router : 192.168.2.1
IP address of Laptop: 192.168.2.101
IP address of 2nd PC : 192.168.2.100  (Problematic)

Now, look at the router's routing table below. 192.168.2.0 network is 
directly connected. However, for 192.168.2.100 it got a gateway address 
through ICMP redirect 84.63.0.1. So in order to reach this sytem it was 
trying the gateway 84.53.0.1. Now i am wondering how this ICMP redirect 
happened? does it have to do something with security?

here is a part of routing table:
------------------------------------------------------------
Flags Network Address 	   Netmask		     Gateway 		Interface
I 	 192.168.2.100 		255.255.255.255 	84.63.0.1 	€9x€܀9X€!܀9L
C 	192.168.2.0 		255.255.255.0 	         directly 		   LAN
I 	 192.168.2.2 		 255.255.255.255 	81.202.40.1	€9x€܀9X€!܀9L

Flags :  C - directly connected, S - static, R - RIP, I - ICMP Redirect
---------------------------------------------------------------------
So i just reset router settings and now it doesn't have 84.63.0.1 as gateway 
for 192.168.2.100. So now both linux and windows are working fine. however, 
i should have saved router's log but i forgot. i have firewalled disabled on 
router. should i turn it on?

thanks everybody,
cheers,
imran.
