Unable to ping after Wireless Configuration using (WRT300N)

HeroVax
Level 1
Level 1

Hello, I have issues with my PC cannot ping to the Internet as well as other PCs. It says "Destination Host Unreachable".

 

Currently, my plan is to create a DHCP Pool using WRT300N Wireless Router. The PC VLAN Security, will then able to access to the Internet and its peers via Wireless LAN that I made using that router. However, it does not ping as I intended. 

Also, the Wireless Router continuously denying my settings and it keep changing my DHCP pool. Example shown below:

I want my DHCP Pool range between 15.0.4.131 - 157. But, whenever I save settings, it automatically changed to 15.0.4.129 - 157 range.

 

I have set up the Router-on-a-Stick for VLAN 40 Security on Router KL. It uses IP Address "15.0.4.129 /27". So, I set up my wireless router as "15.0.4.130 /27". 

 

I have attached my pkt file inside the zip file below for your reference. Thanks.

I change the transit network between WRT and router to 192.168.11.0/24 because you already have the network 192.168.10.0/24 in Penang.  It was causing conflict.

 

The changes I made:

 

KL:

 The interface  GigabitEthernet0/0/0.40 is also using ip address 15.0.4.128/27. So, it was conflicting with wireless network. I disabled it.

Once we disabled it, the network 15.0.4.128 is not advertised anymore to the router Penang.

If fixed that by adding a static route on KL:

ip route 15.0.4.128 255.255.255.224  192.168.11.4

 

Then, on the OSPF I added:

router ospf 10

redistribute static subnets

 

This way, the network 15.0.4.128 was sent to Penang and connectivity started to work.

 

Let me see if you are ok with that and let´s see next steps

Hi

 Keep in mind that wrt is a router, so,  you need to connect it using the internet interface and not Lan interface 

Hello @Flavio Miranda ,

I already use Internet Interface connected to the WRT router.

 

I want to configure my WRT Router as follows:

1.png

 

Internet: 15.0.4.130 

Subnet Mask: 255.255.255.224

Default Gateaway: 15.0.4.129 (This is from Router KL subinterface for VLAN 40 Security)

 

and, I want to have DHCP Pool for VLAN 40 as well:

Router IP: 15.0.4.131

Subnet Mask: 255.255.255.224

Range: 15.0.4.132 - 157

 

It keeps giving errors: overlaps with VLAN1

I didn't configured anything on VLAN 1. VLAN 1 is down.

I looked at your file priviously and the wrt was using Lan interface.  Did you delete the config from that interface ?

No, I did not. I use Copper-Straight Through cable connect from SwitchKL fastEthernet 0/4 to Internet Interface 0/0 

This file attached is working. Wireless client is pinging wired clients.

 

You need to configure one route on the router "Kuala Lumpur"  for the wireless network, which in my case, I used 192.168.1.0/24..  So, on the  Kuala Lumpur router I did:

 

ip route 192.168.1.0 255.255.255.0 15.0.5.130

Hello @Flavio Miranda ,

I checked your pkt file, and it's not quite what I'm looking for.

I was trying to do the DHCP Pool using:

Router IP: 15.0.4.130

Subnet Mask: 255.255.255.224

Range: 15.0.4.131 - 157

 

So, the PC VLAN Security is using that IP Address.

 

Right now, I have created a new VLAN 11 called Internet Connection. And, I have created subinterface gig 0/0/0.11 with IP 192.168.10.3 /24 on Router KL. I created this subinterface because I want to use the IP as a default gateaway for my WRT router.

And, I have added ip static route: 192.168.10.0 /24 , next hop 15.0.4.130 on Router KL. I have also allow switchport access vlan 11 on WRT Router interface.

 

I have configured my WRT router as shown below:

1.png

 

Results: My PC VLAN Security can ping to their peers within the KL Router. But, the PC cannot ping outside of Router KL. It suddenly shows, request timeout on Penang Router.

 

I have attached a new version of pkt file for your reference.

I change the transit network between WRT and router to 192.168.11.0/24 because you already have the network 192.168.10.0/24 in Penang.  It was causing conflict.

 

The changes I made:

 

KL:

 The interface  GigabitEthernet0/0/0.40 is also using ip address 15.0.4.128/27. So, it was conflicting with wireless network. I disabled it.

Once we disabled it, the network 15.0.4.128 is not advertised anymore to the router Penang.

If fixed that by adding a static route on KL:

ip route 15.0.4.128 255.255.255.224  192.168.11.4

 

Then, on the OSPF I added:

router ospf 10

redistribute static subnets

 

This way, the network 15.0.4.128 was sent to Penang and connectivity started to work.

 

Let me see if you are ok with that and let´s see next steps
