I have been struggling for three days now trying to make this setup working:
I want every interface on the router to be on the same network, for example ether1 10.0.1.1/24 and ether2 10.0.1.2/24. I want to do it this way to be able to set a dhcp-server on every interface and set a one specific IP-address on that interface so that connecting something to for example ether1 always gives and IP-address to the client of 10.0.1.100 and for ether2 10.0.1.101. To be able to have it this way I have added proxy-arp to the interfaces so that the clients can reach each other and sometimes this works for a while.. After a reboot it usually don't.
I have reed this text in the wiki:
Two IP addresses from the same network assigned to routers different interfaces are not valid unless VRF is used. For example, the combination of IP address 10.0.0.1/24 on the ether1 interface and IP address 10.0.0.132/24 on the ether2 interface is invalid, because both addresses belong to the same network 10.0.0.0/24. Use addresses from different networks on different interfaces, or enable proxy-arp on ether1 or ether2.
I have tried to have proxy-arp activated on both interfaces and just one but nothing works reliable. Should I use it on both our just one and can I use it on both?
I manage to get it working with VRF but just for a short while..
I need some advice.. Anyone?
