Hi!

I have a internal routed network that my ISP provides. And i have a new ASA firewall connecting to the internet. My ASAs inside interface have IP 192.168.100.2 and ISP router 192.168.100.1. I have configured inside routes on the asa and activated permit intra traffic. That works fine.

But i have some arp/mac address issues. Is this when proxy arp comes in to picture? My clients on the same network as the ASA has problems browsing our domain. When switching to our old vpn network things work well. I can only think of proxy ARP that causes this.

Any ideas?

ps gonna try to switch to the new network tonight with proxy arp disabled.
 
Well it disabled proxyarpen on my internal interface and it works now.
