<div>Hi Noggers,<br>
<br>
</div>
I have a strange issue seems to be isolated to VIC LAC's<br>
<br>
</div>
Some session are coming up at MTU 1476.<br>
<br>
</div>
I did managed to clear a l2tp tun and the session came back via another LAC at 1500.<br>
<br>
</div>
These are the ones i have had problems with: TPGVICLAC-6e / TPGVICLAC-5e<br>
<br>
</div>
To get around it iv set mtu on the dialer to match and used a mss-adjust... <br>
<div>
<div><br>
</div>
<div>I can ping to the LAC's IP at 1500 with no issue.<br clear="all">
