no upload speed in ISP

[nitish14351]

Hii,

We are facing some issue with our ISP. we have 150 mpbs ISP link, there download speed is there, but we have 0% upload speed. Unable to find the reason for this.

We are using cisco ISR4451-X/K9 router.

The configuration of router interface in below:-

interface GigabitEthernet0/0/2 (WAN interface)
 description ## 150 Mbps Mbps Internet Link from BSNL and circuit ID 1000303162 ##
 bandwidth 153600
 ip address 172.24.177.217 255.255.255.252    (ISP IP)
 ip nat outside
 load-interval 30
 negotiation auto
 performance monitor context PrmAM_AVP4_c
 service-policy output parent-policy
!
interface GigabitEthernet0/0/3 (inside interface)
 ip address a.b.c.d 255.255.255.224
 ip nat inside
 ip tcp adjust-mss 1460
 negotiation auto
 performance monitor context PrmAM_AVP4_c

Kindly suggest something

Hello,

the configuration looks ok, although I am not sure I understand your IP addressing - are these all public addresses ?

Either way, on your inside interface, remove 'ip tcp adjust-mss 1460':

interface GigabitEthernet0/0/3
ip address a.b.c.d 255.255.255.224
ip nat inside
--> no ip tcp adjust-mss 1460
negotiation auto
performance monitor context PrmAM_AVP4_c

Also, post the output of:

show interfaces GigabitEthernet0/0/2

show interfaces GigabitEthernet0/0/3

Hiiiii ,

After removing that command, still issue is there. And also find the output you asked for.

Hello,

try and remove the service policy from the interface

interface GigabitEthernet0/0/2
description ## 150 Mbps Mbps Internet Link from BSNL and circuit ID 1000303162 ##
bandwidth 153600
ip address 172.24.177.217 255.255.255.252
ip nat outside
load-interval 30
negotiation auto
performance monitor context PrmAM_AVP4_c
--> no service-policy output parent-policy

and use a site like 

http://www.speedtest.net/

from one of your clients to check what speeds you are getting...

Hello,

it sounds like the problem could be with the provider...have you checked with them ? They can test down and up speeds from their side as well...

Hiii,

I have logged the complaint with my ISP, but still waiting for their customer.

Still meanwhile I am checking that issue is not is router configuration.

If you find anything wrong my configuration, let my know.
