Restrictions to SHARE. Just HTTP service work!

[aRTx]

Hi,
I'm connecting to the internet with a modem, username and password (PPPoE).

I'm trying to share with couple of programs,...

In the (server PC) are working almost all services.

In the (client PCs) is working only HTTP service.

I have choose to allow all of services.

My ISP is trying to stop us to share internet for the others computers.

I can't use my VoIP adapter because it request an IP Address.

With another ISP I have done to share internet but I want to use this ISP because price and benefits.

I'm trying to learn TTL and MTU maybe there is the problem.

My info:

Why the IP ADDRESS and GateWay are same?

Do I need to change the MTU or TTL at server or client?

From Client I can't ping site (i.e ping yahoo.com -t) but I can ping server pc and My Computers on LAN.

FROM CLIENT PC I CAN VIEW youtube.com without problems.

How is your client computer connecting through WinGate? Are you using Proxies, the WinGate Internet Client, or plain NAT?

To sumarise the symptoms you are experiencing
- The client can browse HTTP
- Client can not ping any URL's
- Client can not use any services other than HTTP

It sounds like you have set the WWW Proxy Service in your clients internet browser, but have not setup a secondary internet connection method using NAT or the WGIC.

The WWW Proxy server can only provide your client with HTTP access, which would explain why your client computer can only browse HTTP.

Try setting up your clients with a NAT connection to the Internet through WinGate. This should give your clients full access to the internet.

My ISP is trying to stop us to share internet connection.

I have heard my ISP has use TTL to controll sharing.

Someone has told me to up TTL values for one CURRENT VALUE OF TTL = CURRENT VALUE + 1. I don't know where to change TTL in Client or Server?.

I have ping yahoo.com and wingate.com from SERVER PC.

The TTLs are diferent.

why IP and GateWay are same always?
To connect to internet I have just UserName and Password

Hi, which version of Wingate are you using?

6.2.2 // the latest release?

You should be able to ping from any client if NAT [Extended Networking Service] is installed, if not run the Wingate installation again and install NAT.

The Ipconfig is ok.

For your client PC it should have an IP, mask and gateway, the gateway is the IP address of the Internal NIC in Wingate where the client pc's could connect via a switch.

The Internal NIC in Wingate should only have an IP address and mask, no DNS or Gateway.

I have heard the ISP is filtring by TTL (time to live).
He is trying to stop us to share internet connection.

Is that possible?

with another ISP the WinGate work GOOD!

what to do?

Hi

theoretically if the ISP set all incoming TTL to 1, then only the device that was making the ISP connection would be able to access the packet.

However, those ping traces you sent indicate that this isn't happening (showing TTLs much higher than 1).

It would be very foolhardy/dangerous for an ISP to set TTL to 1 anyway, since that would break routing on your internal network if you had any other sort of PPPoE device etc (i.e. one that had to forward packets).

I presume from the WinGate machine you can surf? If so, then your clients should be able to surf through the proxy at least.

If your clients can surf through the proxy but not NAT, there could be some TTL checking on your ISP for TTL on the packets you are sending, since NAT packets out of your network would have 1 lower TTL value than direct traffic out of your WinGate box. But again this would be dangerous from an ISP, since different OSes have different default TTL values. You can set default TTL value I think in the registry of a computer - you could try setting this to 1 higher on a client machine for a test.

p.s.

is your dialup adapter set as "external" in the network panel in GateKeeper?

[aRTx]

I'm connecting to internet through PPPoE.

My ISP is trying to stop sharing us. (I'm sure about that).

To Change the TTL, we can use DrTCP.

How to know the TTL values ?

I'm trying to use VoIP Adapter LINKSYS and in it I can't use TTL (I can't change ttl for it).



IF I WILL RESOLVE IT, I WILL SHARE WITH YOU.

[adrien]

a simple test is to try ping.

you can set TTL on a ping packet using the -i switch, e.g.

ping www.microsoft.com -i 2

will send an ICMP echo packet with TTL of 2.

If your ISP really is messing with your TTL or blocking based on TTL, then you should be able to quickly test for this by trying to ping with different TTLs from the WinGate machine, and client machines.
