<p>Hi Adam,</p>
<p><br>
</p>
<p>As a rule your mss-adjust should be 40 bytes lower than your actual
MTU. In theory you should have 1492 on the dialer and and an mss-adjust
of 1452 on the LAN interface.</p>
<p><br>
</p>
<p>If you're going to keep 1452 on the Dialer as the MTU you should
adjust the mss appropriately. See if that helps at all.</p>

<div>Hi All,<br>
<br>
</div>
I have had 2 Customers in the last few weeks that have had MTU problems.
This is my Dialer interface.<br>
<br>
interface Dialer0<br>
ip address negotiated<br>
no ip redirects<br>
no ip unreachables<br>
no ip proxy-arp<br>
ip mtu 1452<br>
ip nat outside<br>
ip virtual-reassembly<br>
encapsulation ppp<br>
load-interval 30<br>
dialer pool 1<br>
dialer-group 1<br>
no cdp enable<br>
ppp authentication chap callin<br>
ppp chap hostname <a moz-do-not-send="true"
href="mailto:xxxx@direct.telstra.net" target="_blank">xxxx@direct.telstra.net</a><br>
ppp chap password 7 xxxxx<br>
end<br>
<br>
</div>
I have never had any problems accessing websites until the last few
weeks. Does anyone know what might have changed at the Telstra end? I
had to set "ip tcp adjust-mss 1452" on the Dialer interface to make it
work. Never had to in the past with a number of
other connections. Perhaps I should have all along?<br>
