You can also see this in Winbox : -> open winbox -> left-click "PPP" -> left-click "Interface" tab ( default ) -> double-left-click on your 3G modem interface -> left-click on "Info..." in right menu, almost on the bottom -> make sure that in the "interface" option on the popup window your 3G connec...

Re: Does WAN failover clear old tracked connections ?

I have changed the UDP lower. Can I request this feature ( automatically clearing tracked connections on failover ) for a future release ?

Don't forget to set up your interface for proxy-arp

Does WAN failover clear old tracked connections ?

Does multiple WAN failover ( http://wiki.mikrotik.com/wiki/Two_gateways_failover ) automatically clear the connection tracking of the "old" WAN interface ? I'm asking this because I have a router that has two connections, a wireless P2P link, and a PPPoE ADSL connection. We route SIP and RTP over th...

Re: Problem: Route VoIP (SIP) traffic over another route

I will reply to my own post : I have contacted Mikrotik support ( Maris ) and he has helped me solve the problem. The problem was that I had enabled the new route, but there was still an entry for that SRC nat in the Connections tab of the IP -> Firewall. In other words, connection tracking tracked ...

Re: Split trafic

make sure you queue on the correct interface. It will most likely be different interface for outgoing as for incoming ( that's how I configure it )

Re: Mikrotik and VoIP: Fax T.38 transmit problem behind NAT

thanks very much for this post. It's very useful to me. I have been battling with FoIP for weeks, I'll try and upgrade to 5.1 and see if that fixes the FoIP problem. I can't believe I dismissed the router as the possible cause. So many things with T.38 can go wrong, but I didn't think the router wou...

Re: uTorrent real problem QOS, help

I usually identify bittorrent traffic by the vast amounts of open ports and new connections to a certain PC. But because of their encrypted nature, it's very hard to identify bittorrent traffic. Rather than try and block or identify bittorrent, try and identify everything else, then allow a certain ...

Hi Guys, Sorry , this is about the same topic as the VoIP Sip routing, but I presume the title scared people off. Simply put, my problem is that I have two uplinks on one RB450G router.

Hi guys, Thanks for taking the time to open this post.

Re: modify queue will reset queue statistics and lose packet

Omega and Fewi, Thanks for your replies. I will have a go at changing the script to use other queues. I'll make a few standard queues ( 20 ) and direct traffic dynamically to the different queues.

Re: modify queue will reset queue statistics and lose packet

Omega : Some of our customers use highly unreliable rural ADSL connections. They will have 12000 mbkbps one minute, then it rains and they get 1000kbps. I use a script to change queue sizes depending on how much speed is available. This script runs all the time, and changes queues as needed. It work...

Hi LastResort, thanks for your reply. I understand what you are trying to say, but I must have explained my issue wrong. In order to clarify, let me try to explain again. The packet drop doesn't occur because of the queues dropping TCP packets, it seems to occur because of physical ports being shut ...

Looking for manufacturer of WHITE casings for RB450G

Hi guys,

We're looking to buy WHITE casings for RB450G. The metal cases are fine, but our clients like the white boxes better. Any manufacturer out there who makes the boxes in white, rather than black ?

Cheers.

Re: Anyone had any experience with SIP phones?

no problems with the Mikrotik and SIP. Works out of the box, no need for NAT or anything like it. You should have your ADSL modem in pure bridge mode, and use PPPoE from Mikrotik.

modify queue will reset queue statistics and lose packets

When I change the queue properties ( for instance, I change queue tree from 4000kbps to 3000kbps ) then I see packet loss. It's almost like the interface is undergoing some sort of "on/off" very quickly. The packetloss is minimal, but on voip it' spretty bad, I can hear it. Is there any way to make ...
