We are replacing a Cisco 2600 router on a frame relay circuit that connects to the internet with a Mikrotik and a Cyclades-PC300 T1 interface. I read the manual and added the PVC interface and added an ip address to it, but I can not ping the gateway address from the Mikrotik. I can ping it when the Cisco is connected. Everything pretty much looks the same as the Cisco's config. It says that it is in sync. Does anyone have any idea what I am doing wrong? We would be glad to pay an expert for assistance in this. We need this online today.

Post your Cisco config and export command results from /interface cyclades, /interface pvc, /ip route and /ip address submenus in order to get an answer.

Thanks. Here it is:

DLCI mismatch. Should be

Actually, I had the DLCI correct at one point. It didn't get set back correctly after I deleted and readded the interface. My vendor told me that I was using the wrong level of software. So, I upgraded from 5 to 6. That didn't make any difference. We started going through the settings and changed the active-channels=24 to active-channels=all and it went to working--sort of. I can get out to my provider but that is it. They say that we are sourcing the wrong address on our NATing. Which we are. I don't know how to make this thing do what I want. I have three interfaces now: the T1, my private network, and a "DMZ" network. The T1 interface is a private address from my providers network. The DMZ has my public IPs. How do I create a source-nat entry to give out the correct ip? It keeps giving out a 172.20.16.190 from my T1 interface, which is a private address.

Here's how the Cyclades is set for our frame-relay:

0 R name="cyclades1" mtu=1500 line-protocol=frame-relay media-type=T1 clock-rate=64000
clock-source=external line-code=B8ZS framing-mode=ESF line-build-out=0dB

chdlc-keepalive=10s active-channels=all
