Hi guys,
My ISP is Xilo.net and the default mtu is 1432. I was orginally using a J2320 device with the following configuration.
et interfaces pp0 unit 0 ppp-options chap default-chap-secret "$9$ghJik5T3t0BZUAp0OREs2gJik"
set interfaces pp0 unit 0 ppp-options chap local-name "17815@tw.uno.net.uk"
set interfaces pp0 unit 0 ppp-options chap no-rfc2486
set interfaces pp0 unit 0 ppp-options chap passive
set interfaces pp0 unit 0 pppoe-options underlying-interface ge-0/0/0.0
set interfaces pp0 unit 0 pppoe-options idle-timeout 0
set interfaces pp0 unit 0 pppoe-options auto-reconnect 10
set interfaces pp0 unit 0 pppoe-options client
set interfaces pp0 unit 0 family inet mtu 1432
set interfaces pp0 unit 0 family inet sampling input
set interfaces pp0 unit 0 family inet sampling output
set interfaces pp0 unit 0 family inet negotiate-address
set security flow tcp-mss all-tcp mss 1350
Website load ok.
So Today I went about migrating out of my J series box and into the SRX 110
It is configured so fe-0/0/0 is the port which connects the draytek modem and the pppoe / pp0 adapter dials the connection and authentications.
I can have no issues establising a connection my issues start once the connection has established pages load very slowly with the above configuration some pages dont load so I decided to ditch the J series config and remake one for the srx
This is the srx110 config now
set system name-server 193.150.34.1
set system name-server 91.230.181.1
set system name-server 8.8.8.8
set interfaces fe-0/0/0 unit 0 encapsulation ppp-over-ether
set interfaces pp0 unit 0 ppp-options chap default-chap-secret "$9$VIYJGkqfn9A24369Cu0NdVYJG"
set interfaces pp0 unit 0 ppp-options chap local-name "17815@tw.uno.net.uk"
set interfaces pp0 unit 0 ppp-options chap no-rfc2486
set interfaces pp0 unit 0 ppp-options chap passive
set interfaces pp0 unit 0 pppoe-options underlying-interface fe-0/0/0.0
set interfaces pp0 unit 0 pppoe-options idle-timeout 0
set interfaces pp0 unit 0 pppoe-options auto-reconnect 10
set interfaces pp0 unit 0 pppoe-options client
set interfaces pp0 unit 0 family inet negotiate-address
set routing-options static route 0.0.0.0/0 next-hop pp0.0
With the config like this I can ping google.com -f -l 1432 - This is the correct MTU packet size.
so I added set interfaces pp0 unit 0 family inet mtu 1432
I still have slow internet..
I then decided to play around with
Set security flow tcp-mss all-tcp mss and inserted ranges from 1200 upwards to 1400 - this made very little difference.
I have also tried removing the mtu from the pp0 adapter and only configuring / the mss settings
no matter what i do the pages load slowly.
ideas any one ?
