MSS and MTU values are set to what the tunnel broker requires on the interface, can you also set the MTU inside of Squid configurations? <br id="lineBreakAtBeginningOfMessage"><div><br></div><div><br></div><div>I enabled ping helper I show a good socket for my IPV6 interface address but every IPV6 only device shows NONE_NONE/409 on the Squid Access Table </div><div><br></div><div><br></div><div>I get the same result. How would I change MTU on Squid isn’t that set to auto discover with the HTTP port directive?</div><div><br></div><div>I also forgot to mention the IPV6 only device works when I have it set to not use the proxy. </div><div><br></div><div>Thanks again for the reply. It does work from IPV4 to IPV6 requests but never for IPV6 to IPV6 addresses or pure IPV6.
