I have the following configuration:
Cable Linksys DLink Wireless Modem ------ RT31P2 -------- DI-604 -------- Router ------- PCs NAT & DHCP Router | no NAT | no DHCP | |---- Desktop PC
I'd like to configure the Desktop PC as an FTP server and I have setup port-forwarding on the RT31P2 and the DI-604 routers. It works except that the DI-604 sometimes gets another IP address from the RT31P2 and causes the port-forwarding to no longer work because the IP address of the downstream router has changed.
The RT31P2 sits in front of the DI-604 because the RT31P2 is for voip service and it gives voice traffic priority over other traffic (QoS).
The DI-604 has a static DHCP function that allows me to tie the Desktop PC to a specific address on the DI-604. The static DHCP keeps the Desktop IP address constant.
Is there a way to keep accomplish this?
It would be great if the RT31P2 had static DHCP - perhaps there's another way to accomplish the same function.
Can I configure the DI-604 to have a static address and turn off DHCP/NAT on the RT31P2? A static WAN address on the DI-604 requires I define also DNS server addresses and I'd like to keep getting those automatically.
Any other suggestions?
