Hii..

I'm using buffalo whr-g125 with tomato victek mod v1.21 ND. I have few question to ask. Please refer to pic below.



My question:
1. How do i access my modem and router 2 ? i try 192.168.1.254, but cannot get thru.
2. After using this set up, my speed down drastically. I mean after using router to dial (PPPOE) instead of using Modem to dial . If i use modem, speed = 1MB++ . if using router, my speed = <1MB. any clue ?
3. How to block P2P and Torrent ? I know IP2P and level 7 filter bring lots of load to router, but is there any better way ?
4. I set up my network like this so, the router did not stress up too much. Any comment on this ?.
5. I have set DDNS on router 1 and it works, can i set DDNS on router 2 ? I try but can get it to work.
