I am running Tomato 1.28 and just switched to an ISP that requires an L2TP usage. I've configured the L2TP, everything seemed working, but, surprisingly, i've discovered my mobile phone (HTC HD2) won't sync with google "activesync/exchange" anymore. Reconfiguring the phone's MTU setting to a low value helps. Now to the actual tomato issue... Reconfiguring the L2TP MTU value, even setting it as low as 1000 bytes, while leaving the phone MTU at default (1500?) did NOT help. Kinda seems like the tomato isn't really trying to fragment the packets. I would really like to avoid manually configuring each and every device that joins my network, sometimes the fragmentation as an "automatic" solution is desirable, despite being unoptimal. Any ideas ?
