DFL 210 Routing Issue?
« on: February 16, 2011, 05:00:55 PM »
I have a DFL 210 that has been working fine. However we have switched ISPs so the IP addresses have changed. Currently I can get to the servers in the DMZ using their internal IP addresses.  I cannot ping any machines in the DMZ using their external IP address. I suspect it is a routing problem. From the DFL 210 I can ping machines in the Lan and sites external  to our network.

WAN IP     XXX.251.72.YYY => wan_ip, Gateway wan_gw same address range as wan_ip.
Usable IPs XXX.141.6.0/28  => wannet

I have created addresses for all of the external addresses and have published them in the ARP.
The routing table is below
Interface      Network      Gateway
wanwannet
wanwannetwan_ip
wanall-netswan_gw

I would appreciate suggestions on how I can resolve this configuration problem.

The results for our specific configuration was that the DFL 210 could not be configured to handle the internet configuration specified by our ISP. The router needed to be able to handle two different external subnets. Ultimately, since this was a new internet connection for us they were able to issue us a new interconnect range with all external addresses in the same subnet.

So we are now connected and just have a few minor configuration problems to solve.
