When configuring DUAL wan with ANY asus router you might get an error "your isp dhcp is not functioning properly "
Both wan ip adresses must be in different subnets, for example if I have two ISP's which both give me a 192.168.0.1 router gateway, then an "Your isp dhcp is not functioning properly" error appears.
It seems asus routers contain a bug, because WAN IP addresses should not collision because they are external on two different interfaces, this clearly is a bug. Otherwise this would indicate a security issue if both WAN's could see eachother (beeing in the same subnet).
To me there are two problems:
1) It should not matter that both WAN's have the same subnet
2) The DHCP error is wrong, it should output another error, indicating the REAL problem, otherwise it is too difficult to troubleshoot.
So I ask the fix those two problems, and I hope this post helps others.
