IP addresses

Fri Feb 24, 2012 6:53 pm

Hello,

I have just bought a RouterBoard RB750G. And I am trying to achieve the following:

I have my internet connection going to a switch with a gateway IP 192.168.10.1 (this is fixed in my ISP box, I cannot change it - to much trouble) , then from that switch I have 50+computers, which have static IP addresses from 192.168.10.10...+

The idea is that I would like to put my RB in between those two, so that my computers get internet access through the RB. If possible I dont want to change the IP on the computers, so the idea would be to have the RB have the IP 192.168.10.1, so no changes should be done.

So I have configured that ether1 is connected to the internet, and has the IP 192.168.10.1(ether1 ), next I have added in ip/addresses that ether2 which is connected to my switch for other computers the IP 192.168.10.1/24 (ether2), but this does not work.

On the other way if I give a different range to ether2, it works normally.

Is there any way that I keep 192.168.10.1/24 for both ether1 and ether2. I read that "Use addresses from different networks on different interfaces, or enable proxy-arp on ether1 or ether2." but I tried to enable proxy-arp but nothing changes.

Thank you for time.

Regards,
Adnan

You don't want to change the IP addresses in the client computers? Then how about if you just bridge the ether1 and ether2 ports?
