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

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
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.
