Hello Maybe a little more explanation might help. Example setup: - Client PC -> Dialin -> MAX -> Network -> PC Server. Client PC is given IP address 192.168.1.1/32 All other Client PCs will be given IP addresses from 192.168.1.1 to 192.168.1.254 MAX IP address 10.0.0.1/8 PC Server address 10.0.0.2/8 The /8 is the subnet mask. In radius, if you don't enter it in the radius entry, the MAX will assume /32 Possible problem: - PC Dials up and can ping MAX 10.0.0.1, but not PC Server 10.0.0.2 Solution:- Add static route entry to PC Server:- route add net 192.168.1.0 mask 255.255.255.0 gateway 10.0.0.1 Next example:- Client PC -> Dialin -> MAX -> Network -> Router -> PC Server. Client PC is given IP address 192.168.1.1/32 All other Client PCs will be given IP addresses from 192.168.1.1 to 192.168.1.254 MAX IP address 10.0.0.1/8 Router as IP address 10.0.0.5/8 on the left, and 11.0.0.5/8 on the right. PC Server address 11.0.0.7/8 The /8 is the subnet mask. In radius, if you don't enter it in the radius entry, the MAX will assume /32 Possible problem: - PC Dials up and can ping MAX 10.0.0.1, but not PC Server 11.0.0.7 Solution:- Add static route entry to PC Server:- route add net 192.168.1.0 mask 255.255.255.0 gateway 11.0.0.5 Add static route entry to Router:- route add net 192.168.1.0 mask 255.255.255.0 gateway 10.0.0.1 Next example: - Setup when Client PC has IP address 10.0.0.3. I.E. on the same subnet as the PC Server. Client PC is given IP address 10.0.0.3/32 MAX IP address 10.0.0.1/8 PC Server 10.0.0.2/8 Possible problem: - PC Dials up and can ping MAX 10.0.0.1, but not PC Server 10.0.0.2 Solution:- Turn on Proxy-ARP on the MAX. Special Note: Proxy-APR should only be used if one positively has to. Avoid it if you can. I.E. Use first scenario! Also Note: Proper understanding of IP Subnetting is required to adjust these examples to the real world. You CANNOT use just any numbers for IP addresses.
