Help with routing

Hi guys

 

I'm struggling with packet tracer on an exercise and have not been able to identify why the router can not route traffic to a second wireless router

 

Unfortunately I'm not allowed to attach a packet tracer file here

 

Background info:

PC-PT 192.168.1.1

WRT300N Wireless Router 192.168.1.254 (public IP 147.8.1.1)

ISP Router FA0/0 147.8.1.254

IS Router FA1/0 203.1.2.254

Webserver 203.1.2.100

 

In short it is

PC --> Wireless Router 1 --> ISP Router --> Webserver

At this stage, I'm able to ping the webserver 203.1.2.100 and also access the webpage of 203.1.2.100

 

What needs to happen is

PC --> Wireless Router 1--> ISP Router --> Wireless Router 2 --> 2 Webservers

 

The wireless router 2 & the 2 web servers is a company. They have only 1 public IP which is 203.1.2.100, so port forwarding should be used, so when ever users access port 80 on 203.1.2.100 goes to webserver 1, and when they use port 443 on 203.1.2.100 it goes to webserver 2.

 

I have played around for 5 hours, and can't get past the 2nd wireless router issue. The moment I add the second wireless router, i can no longer ping to the 2nd wireless router from the pc. All other hops "before" the wireless router works perfectly. I'm at a dead end and don't know anymore what I'm doing wrong. 

 

Note: Before adding the 2nd wireless router, everything works. So I am pretty sure that the settings on the PC, Wireless Router 1 and ISP router are correct. I was able to ping the webserver. But as soon as I include a 2nd wireless router behind the ISP router, it all goes bad. I can ping from PC to Wirelss Router 1, from PC to ISP Router FA0/0 and FA1/0, but can not get further than that. So for some reason the ISP router does not route my package to the 2nd wireless router or even further. 

 

I would certainly appreciate some help here guys. If need be, I can send the packet tracer file to you 

 

Some info from the ISP router:

Router>show ip route

Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP

i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area

* - candidate default, U - per-user static route, o - ODR

P - periodic downloaded static route

 

Gateway of last resort is not set

 

C 147.8.0.0/16 is directly connected, FastEthernet0/0

C 203.1.2.0/24 is directly connected, FastEthernet1/0

Hi

Have you tried enabling Rip version 2 on all the routers?

 

configure terminal

router rip

version 2

network 0.0.0.0 <--- you could configure this line to test connectivity and probably any network is missed.

 

:-)

If this was working before you introduced the wifi 2 rtr obviosuly you need to be looking at that device intrems of its configuration and it relation to the ISP.

 

What i am not so sure on is where does this Wifi2 rtr reside, if now its infront the of webserver which it has to be then what was allowing access to the webserver before wiif 2 introduction?

 

Can you please clarify this.

It seems you have nat enabled on wifi1 rtr already for the PC lan subnet
