Hello all, I'm new and thanks in advance for any help I might recieve here. To make something quite clear, my connection is WORKING, I'm just making sure I have a sensible setup, and that heavy p2p connections wont crash my system. My current setup is as follows: D-Link DSL-320T ---> WRT54GS (DD-WRT Micro) ---> Rest of network 192.168.100.1 --- 192.168.0.100 ---- 192.168.0.* I am in the UK and have a PPPoA only ADSL conenction to Nildram (GetADSL). I have the D-Link modem setup to connect to PPPoA, with all the settings entered correctly. I have a static WAN IP of 22.214.171.124, which registers correctly on the D-Link. I also have DCHP on the D-link enabled, and the WRT54GS internet mode is set to DHCP (Automatic). It correctly recives the WAN IP of 126.96.36.199, and provides DHCP to the rest of the network perfectly. Everything is working fine. As I have a static IP on WAN, I've set the DHCP timeout from the modem to be 60 mins. The thing that worries me is I have read the following http://www.csc.liv.ac.uk/~greg/projects/dlink.html and the thread at http://www.linksysinfo.org/forums/showthread.php?t=53258 and I'm worried that I have a "double NAT" situation that might cause ARP problems with heavy p2p connections. Will the fact that the modem and router are on different subnets help? I tried putting the modem in bridge mode and it worked for one evening (how it did this I have no idea - how did it now my connection username and password? Bridge mode did not ask for them!) but then it failed and now I'm back in PPPoA mode with DHCP. Thanks for reading this, sorry if it comes across a little disjointed, I just wat to cover all aspects.
