Philip,

Thanks for your reply.



That's what I'm trying to determine/configure. As I mentioned, everything is in Japanese so it's not easy to determine what's going on. Based on the fact that it works on my internal modem (dial-up) and not on the router, I would say that this is where my problem is.




I'm using the same ISP for dial up and ADSL so I don't think they are blocking port 80. Unless it's blocked for ADSL and not for dial up.

So now I need to determine how and where my router is forwarding to. In my PPPoE settings I have the following configuration options I can select -

Operation Mode: Set to NAT Router (Choices are - NAT Router, IP Router, Bridge, GapNAT, Multi GapNAT).

LAN side IP Settings:Various LAN and DHCP Server Settings.

ADSL sise IP Settings: Set to PPP (Choices are PPP or IP Addressing with field to enter IP).

PPP Account Settings: ISP username/password, etc.

PPP Automatic Connection Settings: Automatic connection/time out settings.

UPnP Settings: Option to use or not use with fields to add IPs.

Access Restrictions: Looks like I can enter IPs to restict access.

IP Static Route: Nothing set but I can add up to 32. It asks for - Address/Mask, Gateway Address, Hop Count 1-15.

NAT Address Translation: Nothing set. See my original post for details.

NAT Address Port Conversion: Nothing set. See my original post for details.

IP Filter: Filtering for Private Address, TCP session, Windows traffic, etc. Settings include -
Number: Preset number (no field)
Priority: Field for number (Any number except 0).
Interface: Choice of - From LAN, To LAN, ISP(From PPP), ISP(To PPP)
Origin IP Address/Mask: Field for IP address and mask.
Destination IP Address/Mask: Two radio buttons - Use IP Addrees (enter address/mask) or Use pre-set (LAN or PPP/ISP Acquisition)
Protocol: Field (but I don't know what to enter. Most fields have "*" and another one has TCP-SYN).
Origin Port: Field (but I don't know what to enter. Most fields have "*" and others have a port range).
Desination Port:Field (but I don't know what to enter. Most fields have "*" and others have a port range).
IP Filter Action: Choice of - Pass or Not Pass

Currently the following Filters have been set -

(Number, Priority, Interface, Origin IP Address/Mask, Destination IP Address/Mask, Protocol, Origin Port, Desination Port, IP Filter Action)
1 50 Destination Connection from 1 10.0.0.0/8 0.0.0.0/0 * * * Not Pass
2 51 Destination Connection from 1 172.16.0.0/12 0.0.0.0/0 * * * Not Pass
3 52 Destination Connection from 1 192.168.0.0/16 0.0.0.0/0 * * * Not Pass
4 53 Destination Connection to 1 0.0.0.0/0 10.0.0.0/8 * * * Not Pass
5 54 Destination Connection to 1 0.0.0.0/0 172.16.0.0/12 * * * Not Pass
6 55 Destination Connection to 1 0.0.0.0/0 192.168.0.0/16 * * * Not Pass
7 60 Destination Connection from 1 0.0.0.0/0 0.0.0.0/0 TCP-SYN * * Not Pass
8 65 Destination Connection to 1 0.0.0.0/0 0.0.0.0/0 * 137-139 * Not Pass
9 66 Destination Connection to 1 0.0.0.0/0 0.0.0.0/0 * * 137-139 Not Pass
10 67 Destination Connection to 1 0.0.0.0/0 0.0.0.0/0 * 445 * Not Pass
11 68 Destination Connection to 1 0.0.0.0/0 0.0.0.0/0 * * 445 Not Pass
12 69 Destination Connection from 0.0.0.0/0 0.0.0.0/0 * 137-139 * Not Pass
13 70 Destination Connection from 0.0.0.0/0 0.0.0.0/0 * * 137-139 Not Pass
14 71 Destination Connection from 0.0.0.0/0 0.0.0.0/0 * 445 * Not Pass
15 72 Destination Connection from 0.0.0.0/0 0.0.0.0/0 * * 445 Not Pass

Anyway, I've got no idea which one of the above options can be configured to forward incoming port 80 from wan to internal port 80 on that IP.
Any ideas?
Which option usually handles port forwarding (NAT, Filtering, ???)?
Thank you.
Simon.
