NSX-T NAT Problem

[mehrantgs]

Hi everyone

I'm using NSX-T 3.2.1 and something weird has happened to me after using NAT. some websites do not open! (in 3.1 i had same problem)

Ping and name resolution work fine

I have used different internet links from different providers and even I implemented in other datacenters but the result was the same

when I use this IP on a vm connected to a VDS-backed port group i can reach those web sites

I have used different vlans for Host and Edge TEPs

I used live traceflow and it shows packets are delivered to the destination

MTU has been set into 1700

for example i cant open google.com but don't have problems opening MSN.com

thanks in advance for any help

Hello,

some web sites cant open at all times (like google.com) or just sometimes (ie you need to try couple of times)?

what's the setup on Edge nodes - ECMP in place? What is setup for uRPF on T0 uplinks?

Thank you,

Dragan

Hi dragance

Thanks for your reply

ECMP is not Running on the Edge nodes, URPF is set to strict and even when I put one of the edges into MM, the result is the same. it has happened more than one time to me. I mean I think it's not just like a problem with target websites.

Thank you
