I am somewhat of a newbie at this, so please be patient with my explanation:
I am setting up a Mikrotik router using a PC. Lets say it is at IP 1.2.3.4. ( I actually have a full block of class C). I have another NIC in it that I have assigned 192.168.1.1. I am trying to set that interface to do DHCP with a pool range of 192.168.1.2-192.168.1.100. I have a cable attached to that port to a Ethernet switch. I have a Windows XP PC attached to that same switch. I have a link light on both ports on the switch, and link lights on both network cards on both machines. The PC is being assigned an IP in the correct range (although it is always assigned the highest possible number - is that normal?).
My problem is that I cannot ping from the PC to the router, or anywhere else.
On the router I can successfully ping my gateway router and DNS box. I cannot ping the above mentioned PC.
I don’t exactly know what the problem is. I am using the Winbox PC interface for the router. It works great.
Have you tried running the DHCP setup wizard? In the “IP” Menu, click on “DHCP Server” and in that window on the “Setup” button.
This will start a wizard to configure a complete DHCP server including the necessary IP pool etc.
I tried running the wizard. Any type of IP pool I try to enter in the addresses to setup box, I get an invalid pool message. I am trying anything, such as 192.168.1.2-192.168.2.100.
So instead of using the wizard, I just went through and manually set it up.
Using the wizard - Am I supposed to put anything in the below box? I have been just clicking on the up arrow button to make it disappear. I just need one pool.
OK, I didn’t have my subnet mask declared in the address list page for 192.168.1.1
I put in 192.168.1.1/24. Now from the Windows PC attached to a switch attached to that interface (I named it Office-network), I can ping the gateway (192.168.1.1), I can ping the MT router (68.95.x.x). But I cannot ping my Gateway router, or anything beyond the MT.
However, on the MT (using Winbox), I can successfully ping out to the Internet. and I can successfully ping the Windows machine above.
I’m getting closer. Any more help would be greatly appreciated,
are you using some sort of nat masquerading? it is required, sorta, to get access from your pc to sources on the other side of the MT router. check out http://www.mikrotik.com/documentation/rosmE.pdf on page three for more info.
Yes - I finally found that masquerading was required for the local machines to “see” the outside world. After I entered the command, it started working correctly.
However, the performance seems a bit slow. Is there anything I can check concerning performance?
This MT box I am building is going to replace a FreeBSD box that does the same thing.
My MT hardware:
Dell Optiplex GX100
Celeron 533
128MB RAM
3GB hd.
I know it is not much hardware wise. The BSD box is slightly faster processor with more RAM. If adding faster processor/more RAM will make a significant performance gain, please let me know. Or if there is a MT setting(s) that will do the same…
ok, I added more RAM, it seems to be running fine now. On one of my interfaces I am running a wireless PTP link. On the remote end I have a Ascend MAX with dial-up internet access. I have a central Radius server setup here at my main location which authenticates the remote MAX box users. However, since I switched over to MT router, it seems to be ignoring the radius request. Users just time out.
Any suggestions?
I am on a serious time constraint here, so any help would be greatly appreciated.
