Hello all, please forgive my newness to this. I am learning as i go.
I have a full class C of public IPs. lets say 100.101.102.x/24
My gateway Cisco router is at 100.101.102.1
My Primary DNS is at 100.101.102.3
My MT router is at 100.101.102.4
The MT router has 4 NIC interfaces on it. They are:
public gateway - out to the cisco router
office-network - DHCPed network for office PCs.
PTP-B - a wireless PTP to a dial-up POP
PTP-H - a wireless PTP to a wireless POP
office-network 192.168.1.2 192.168.1.254 - pool for office PCs
PTP-H pool 192.168.2.10 192.168.2.254 - pool for wireless customers
Routes:
DEST GATEWAY PREF SOURCE DIST INTERFACE
AS 0.0.0.0 1001.101.102.4 (blank) 1 public gateway
DAC 100.101.102.0/26 (blank) 100.101.102.4 0 public gateway
DAC 100.101.102.128/26 (blank) 100.101.102.129 0 PTP-B
DAC 192.168.1.0/24 (blank) 100.101.102.129 0 PTP-B
DAC 192.168.2.0/24 (blank) 192.168.2.1 0 PTP-H
As you can see, the dynamic routes are messed up. I do not know how to fix them. Or if I could put in a simple static route for each and delete the dynamic route, that would be fine too.
Please advise,
I know this setup needs work.
Please forgive, all info taken from Winbox screen.
These are not dynamic routes, they’re routes to directly connected networks.
The issue is that you have an address overlap between your public network and PTP-B. In addition, you have the broadcast address for your public network defined incorrectly.
Public gateway is 100.101.102.4/24 which means that the broadcast address is 100.101.102.255 and not 100.101.102.63
The end result of this will be that the router is very confused about which networks are connected to which interfaces.
What version are you running? If not current then upgrade.
What happens to these routes when you reboot the router?
Do you have bridging setup on any interfaces?
Anything else you haven’t told us that might be relevant?
If all else fails, reset to a default configuration and add the IP addresses to the ethernet interfaces and see what the routing table looks like. Then add the rest of your config in line by line until the routing table breaks.
I remember something like this. But it was fixed long time ago by MT. I suggest you to upgrade to latest version. Probably you are running unfixed version.
