Hi all

Ever since I have VF UFB installed, I have had issues  every 2-5 days where the DHCP client fails to renew a new IP address on the WAN port (ONT facing) side of things. With no IP address, comes no internet connectivity!

Has anyone else had this issue?

It seems to come right after a few minutes (most of the time) however it is a pain as we rely on it for our VOIP.

I am thinking about ringing VF support, however I am using a Mikrotik RB2011 instead of their supplied router, which they won't support.

Yes I get the same thing every now and then, resolves after a minute or so.

1) Are you using a custom DNS (like a Netflix unblocker?) - sometimes these can take a while to catch up with your new IP.
2) Under your PPPoE connection what have you got your keepalive set as? Try setting it to 30sec and see if this helps (Interfaces, your PPPoE interface, Dial-out).
3) What version of RouterOS have you got? Make sure it is up-to-date (http://mikrotik.com/downloads)

Hi Michael

1. No using VF's default DNS servers. (I do have a few VPNs connected (l2tp) for specific Au and US traffic - doesn't affect general though)
2. I don't use PPPoE. Just DHCP bound to the VLAN10 interface
3. version 6.17. I will schedule an upgrade end of the month if the change log stacks up.

So you still get it or have you managed to fix it? I wonder if others who use the HG659 VF supplied router have the same issues... Might temp me to move back onto it....

Ah interesting, I'm on Spark who use PPPoE (with port-based authentication) so have a slightly different setup, also using a RB951G-2nHD. I'd say the problem is with the NAT rules / the IP changing, I've seen this happen on other routers but not to the extent the Mikrotik can sometimes do it for. I think the solution for the "more advanced" who notice it is to get a static IP. I am also running 6.19 at the moment.

Never got it fully figured out however I've got my router to only drop internet for about a minute when the IP changes, the minute is simply caused by (for me) the router having to pass its now IP over to my DNS unblocking service so they continue to answer my DNS from what I see.

Vodafone really are locking down their UFB services to their own hardware and do use a number of DHCP options as well.

Having heard some other dramas recently (not on here and I'm not going to post specifics) my recommendation would be to not sign up with Vodafone UFB if you don't plan on using their hardware.
