- ASUSWRT's Admin GUI only supports single logged-in session. If you closed the admin GUI on one computer, you will not be able to login on another computer unless you log out the GUI session from the first computer.
- ASUSWRT's QoS does not support classification based on source port. It is critical for remote admin on a router swamped with traffic. On Tomato, you can set TCP 8080 highest to ensure you remote admin session from office to home router is always responsive.
- ASUSWRT's QoS rules can not be re-ordered for best execution efficiency.
- When configuring ASUSWRT without WAN port plugged in, the admin GUI is very slow.
- ASUSWRT only has PPTP VPN server and client. There is no OpenVPN support.
- ASUSWRT's QoS does not have the useful QoS gragh/pie chart.
There are actually tons of features in Tomato that you may find useful but can not be found in ASUSWRT. Nevertheless, it is a good thing for average home users who just want to set up and go in a few minutes. And QoS in ASUSWRT works well while most of QoS in other home routers fail. For people who wants and enjoy tweaking, Tomato wins hand down.
I eventually flashed Tomato Shibby into my RT-N10P bought for $10 from TigerDirect, and have a big smile on my face.
