Please report the output of:
ip addr show
netstat -nrThese will tell us what interfaces and routes are *actually* being set up on your Dach router, not what you are *trying* to set up (in the end, that is all that the config files tell us). If the extra-address interfaces do not show up, or there is a problem with routing back to them ... well, then we can try to help you figure out where you went wrong. But it's quickest to check the actual settings before starting out on a possible snipe hunt for config-file errors.
One blue-sky thought ... I've never tried to set up one of these multi-address external interfaces where the extra addresses are on a different network than the primary address (and the default gateway). I wonder if packets going back out those interfaces can find the default gateway? (Charles, are you around??? How does that part work on Dach?)

Thank you for your reply Ray.[old stuff deleted]
You are correct in your assumptions. I have not tried to route the pcAnywhere stuff from my primary IP. That is a test that forgot about. :-) I also was stupid in thinking that if I tried to ping one of my secondary addresses from an internal computer that I would get a valid result. Obviously, that's not the case. I am taking your advice and going to look at the routing stuff to see why packets are not getting to my firewall. I think you're right about this not being a port forward issue.
I saw the DNS stuff late yesterday afternoon and called my ISP about it. I know who owns the msdcomputers.com domain, so I called them too. My ISP said that the problem is that they have not updated their reverse lookup stuff, but would get it fixed soon. I don't think that is causing the problem though, because the packets get routed correctly when I've got my Windows Server 2003 box running.
I've set up the following information about my external interface:
eth0_IPADDR=206.127.76.231 eth0_MASKLEN=27 eth0_BROADCAST=+ # Use this to set the default route if required - ONLY one to be set. # routed or gated could be used to set this so only use if not running these. eth0_DEFAULT_GW=206.127.76.225 # Secondary IP addresses/networks on same wire - add them here eth0_IP_EXTRA_ADDRS="206.127.77.48/28 206.127.77.50 206.127.77.51 206.127.77.52 \ 206.127.77.53 206.127.77.54 206.127.77.55 206.127.77.56 206.127.77.57 \ 206.127.77.58 206.127.77.59 206.127.77.60 206.127.77.61 206.127.77.62 \ 206.127.77.49"
# Additional routes for this interface, if any # Space seperated list: <PREFIX>[_<more ip route options>] #eth0_ROUTES="1.1.1.13 2.2.2.0/24_via_1.1.1.18" # IP spoofing protection on this interface - YES/NO eth0_IP_SPOOF=YES
Is there more that I have to do for routing in Dach? Do I have to configure eth0_ROUTES to make this work properly? If so, could you please tell me what I should enter here?
Thanks a lot for your help, Ray. I appreciate it.
