EoIP configured by DHCP

RouterOS General
1

Hi,

I’ve just moved over to a new ISP, and they require connection over EoIP, but want to hand out IPs per connection via DHCP.

So, I need to configure an EoIP link without an IP in Mikrotik, and then run a DHCP client over that link to establish my internet connection.

I’ve managed to set most of this up, but my DHCP Client broadcast goes nowhere. I’ve plugged my ISP’s ethernet line into ETH1, and I’ve configured an eoip-isp interface with 0.0.0.0/0 as the destination IP, and I’ve configured my DHCP client to find an IP for the eoip-isp interface.

The DHCP Client broadcasts to 0.0.0.0 for a boot request, but obviously, those packets don’t know to go out of ETH1. I haven’t been able to find the correct place to configure this (routing doesn’t seem to work, since there is no destination IP)

Any ideas?

Is your EoIP link running?

Can you paste an export here? Or screenshots?

I think you should get some management ip on ether1 then while not having a default route there open an eoip tunnel with another ip on its end and use that tunnel as wan interface. Your isp should provide you a configuration procedure how to set your client side correctly.

Thanks for the feedback. I managed to realise that I do need an IP on ether1 before initiating the EoIP link.

I had tried to run a DHCP client on ether1 previously without success, but it turns out my ISP grabbed the first MAC that requested an IP (their supplied cheapy) and ignored all subsequent requests from my Mikrotik.

Solved by cloning the MAC of the first router. What a pain!
