One question, for BIZ20 fixed IP, do I just use normal PPPOE as I would for VIP5 dynamic IP? Or is there a proper way to configure fixed IP (with PPPOE authentication)?

One more, can I delete the DHCP Client that's running on ether1 (the WAN port)?

anybody using RB751U-2HnD

and have some weird problems ?

like this ?

You just want to do port mapping or DynDns?

You try to use the same url for the local ip? I have not done this, but usually when using same fqdn, we translate to local ip, instead of using publicl ip.

try

/ip firewall nat add chain=dstnat protocol=tcp dst-port=8060 in-interface=ppoe-out1 \ action=dst-nat to-addresses=192.168.1.10 to-ports=8060
in-interface= your missing?

But you may have problem if your ip change.

What's new in 6.0beta1 (2012-Apr-13 15:26):

*) updated drivers and kernel (to linux-2.6.38.2);
*) improved interface management (scales well for up to thousands of interfaces and more);
*) improved queue management (/queue simple and /queue tree) - easily handles tens
  of thousands of queues;
*) improved overall router performance when simple queues are used -
  at least double the performance of v5, even bigger improvements on multicore systems;
*) very small overhead for packets that miss simple queues,
  but simple queues are present in the system;
*) pcq queue is NAT aware (just like "/queue simple" and "/ip traffic-flow";
*) in "/ip firewall mangle" can specify "new-priority=from-dscp-high-3-bits";
*) new default queue types: pcq-download-default and pcq-upload-default;
*) simple queues have separate priority setting for download/upload/total;
*) slave flag shows up for interfaces that are in bridge,bonding or switch group;
*) global-in, global-out, global-total parent in /queue tree is
  replaced with global that is equivalent to global-total in v5;
*) simple queues happen in different place - at the very end of
  postrouting and local-in chains;
*) simple queues target-addresses and interface parameters are joined into one
  target parameter, now supports multiple interfaces match for one queue;
*) simple queues dst-address parameter is changed to dst and now supports
  destination interface matching;
*) dns cache logs requests to topics "dns" and "packet";

Using LAN cable I get the speed - in fact 10% faster 22-24mbps.
Its the wireless thats screwed.
