Bug 1:
You cannot use nstreme1 modes 
any configuration for it is not used
demo2.mt.lv uses Nstreme1, check it out …
ok… maybe this is an winbox problem… it unsets nstreme checkboxes and the default-forward checkbox…
But i’ve downgraded to start the link working when I saw the default-forward
actually the 2.9.3 has some important fixes, so I recommend you to test this version and send supout.rif files in case you still find some problems
winbox can’t configure fragment matcher properly (winbox glitch)
does the router defragment packets going through the router? if i drop all fragments in firewall, would it still reassemble them before they get dropped?
how does that bit work?
Only without conntrack enabled.
i take it you mean that when conntrack is enabled it will defragment? When conntrack is disabled it will not defragment?
That’s great, works!
yes, it should be something like that, sten
Problem after Upgrade to 2.9.3 from 2.9.2…
Default ACL on Wlan IFs was set to reject… I could not change it to whatever no matter what…. Always reject! MAC Filtering DEFAULT ON and Reject ALL??? What were you thinking? 
As a result I downgraded! To 2.9.2
I bet WISPs will have a great time hoping on their musts and downgrading their routers…. 
winbox checkboxes don’t work, we have fixed this, wait for patch (today)
Nice… Good work Guys … Thanks for the greatly quick response!
True, but…
Didn’t this surface before 2.9.3 was released…? 
What’s new in 2.9.4:
*) fixed WinBox configuration problems;
*) added multiple ip address support for dns-update;
What is “added multiple ip address support for dns-update;” ?
Can I use DHCP to set an interface to have multiple IPs ?
Can I assign multiple IPs if I’m using PPPoE with Radius ?
“added multiple ip address support for dns-update;”
This was added to allow round robin ddns updates. We will be offering a inbound load balancing solution here very shortly.
More specifically you can use /tool dns-update address=x.x.x.x,y.y.y.y,z.z.z.z and our ddns system will setup round robin based on what connections you have available.

Do you have some further information on this??
