I have a problem, current i have two computer, one is at office & one is at home. At office, i use ADSL, which apply from ISP at Malaysia(Tmnet). I have a cellpipe router, and an IP for the computer. At my home, i have computer, using ISDN dialup, which has fixed IP. Currently, i need to use PC Anywhere version 10, however, it didn't work.

i use Ping command, but it is unable to ping, in either way? is this the main problem? why can't both of them ping each other? both can go to internet without problem.

1- if the cellpipe router does NAT (network address translation) you won't be able to ping from internet to computers behind that router. What is your IP address?
2- ISDN dialup with a fixed IP is highly unlikely. Check with your ISP if this is really the case.

1. How to make the configure the router to disable NAT, so that i can ping from internet to computer?

2. I have applied the ISDN dialup, from ip configuration, i see that everytime i dial-up, i still use have the same IP address, and it didn't change.

i would like to know whether there is any restriction at ISP which not allowing the customer to communicate with each other?

It is possible to disable NAT, but then you would have to purchase two additional IP addresses for you internal network (between the router and your computer). The purpose of NAT is to get more devices (routers, pc's) on one internet connection.

NAT uses private internet addresses (10.x.x.x, 172.16.x.x, 182.168.x.x). If your IP address has one of the above forms you cannot ping it from the internet.

It may be that your ISP is restricting communication to dial-up connections, but you would have to check with your ISP yourself.

If you can't change the router setup, and you do indeed have a private internet address (do you?) you won't be able to connect to it from the outside. (Positive effect: you won't be attacked either...)
