I guess what I am really asking is not is there a solution to avoid routing, but how is it done in the real world? What is the proper way to do it? If I do one of the above, am I implementing a hack to get around an ISP restriction, or should it be done using routing, or is this the way everyone does it?
I know that ISPs sometimes make such funny statements. Well, of course there is a chance to hack it that it will work - but who likes an unclean uplink? Proxyarp can be nice in some cases, but I wouldn't like it on a firewall... I would suggest you to find a web page describing basic IP routing, search for a nice URL like ipfordummies or such :) and post the link to the ISP. Give them a backdoor like "it seems that you misunderstood my configuration" and send them the routing table entry. I know that problem, and I know ISPs that told they had updated their routers configuration, but do not trust them - use arp and of course tcpdump to check if they did. And if it works, poweroff and poweron their router, and if it stops working after it, post them that you had a powerloss and it stopped working and kindly ask if it would be possible to permanently store the bloddy config in their damned router. You may think it's funny, but we had such a problem with a non-permanent routing entry and had a complete fail after a powerloss! Do not assume that the ISP contact person knows anything about IP... Maybe you can get tech contacts. oki, Steffen -- Dieses Schreiben wurde maschinell erstellt, es trägt daher weder Unterschrift noch Siegel.
