DHCP lease is in the order of days..can't remember exactly how long. It normally takes at least a week or two before things start to slow down. On 14 Aug 2015 7:28 am, "Jason Hecker (Up & Running Tech)" < jason@upandrunningtech.com.au> wrote:
How long is the DHCP lease? How long does it take before things go awry?

I did have one case where I reinstated the cable modem as the main router and made the mikrotik CRS into an unmanaged switch. There have been no reported problems since then.
I really feel this is somehow to do with the DHCP client/server interaction between the two devices. I have even tried running the modem non-bridged so that there is a dual NAT situation which gives me a very similar result. Maybe the Cable modems are expecting a certain field to be present in the DHCP challenge/response packet and the mikrotik is not providing this information ? Something like that anyway?

All the DSL modems are running in full bridged mode already with the Mikrotik doing the authentication. The cable modems are also set up in "bridged" mode which essentially means that NAT is switched off. Either way, the Mikrotik ends up with a public IP on it's WAN-facing port.

Can you run the modems in a PPPoE bridged mode?

OK all the problems are back. I'm still getting customers whose networks are grinding to a halt after making the changes I detailed above. As always after changing the config, everything seems to run great for a few weeks and then everything falls over in a heap again. If I run direct through the modem (any DOCSIS version) the speeds return to normal immediately.
I did find this post on the forum http://forum.mikrotik.com/viewtopic.php?t=95441 which I've yet to try in a controlled environment.
Someone somewhere HAS to be expereincing this same issue - it's happening with too many customers to be a coincidence.
You guys have checked my config and no-one has flagged anything as being immediately wrong so I'm really at a loss. The only other common factor here seems to be SONOS and I am talking to playback about any issues they may have seen with MikroTik (which they unofficially recommend).
