Strange issue with WinGate 6.0.4.1025

[Maxsit]

Hello,

I'm currently testing WinGate 6.0.4.1025 (Trial) on Windows NT 4.0 Workstation (English) with SP6a (High Encryption), Sequrity Rollup Package and IE5.5 (with SP1) installed. I spent several days on this problem, I read manual and this didn't help me. There is strange issue with WinGate (may be it's a bug). Description:

I have 3 dial-up entries (3 ISP's). They all work when WinGate is not installed. After installing WinGate with ENS (doesn't matter ENS enabled or disabled) only one certain entry of three dial-up entries works fine. I'm testing Internet connection on the WinGate Server PC (direct and using proxy) and on Client machine (using proxy) by entering URL in Internet Explorer. With one dial-up entry everything is ok. With two other entries I can't open URL in Internet Explorer, BUT on WinGate Server PC PING command works fine (for i.e. I can ping yahoo.com). I don't have any firewall installed. It is clean operating system.

When I install without ENS or disable ENS and ask to not load at system start (the driver isn't installed) all entries work fine. May be there is something that I missed, but it's strange that two of three entries don't work not all at the same time. Could you please give me some comments on this issue and if you need anything else from me please let me know.

Hi

With WinGate not running, if you do a route print command from the command line when all 3 dialup connections are connected, what do you see for the default routes? I'm specifically interested in the route metrics.

WinGate automatically sets all route metrics for default routes to 1. This is from a while ago where it was the only way to get more than one dialup working, but since we now have the ENS driver (since WinGate 4.5) it's no longer needed. So we have taken it out for the next release.

If you would like to try with this one let us know - we plan to release it mid next week.

Regards

Hi Adrien,

I have to clear: I don't connect all three dial-up entries at the same time, but only one. I have only one modem, but three dial-up entries. I use them one by one, not simultaneously.

Hi

What values show up for MTU in these dialup connections in GateKeeper when you are connected?

I am suspicious that this could be an MTU issue.

Can you ping through WinGate on all connections or just the one?

e.g. does this block only HTTP, or all service?

Sorry, I can't get it right now.

> I am suspicious that this could be an MTU issue.
What is the solution if it's an MTU issue?

> Can you ping through WinGate on all connections or just the one?
I can ping only on one connection, BUT it seems that DNS service is working on all connections (When I do PING of the host name I can see its IP address in PING output).

> e.g. does this block only HTTP, or all service?
It blocks all services, but I can get IP address by host name, so I can see what IP address host name has when pinging.

That means that UDP is working, since that is what DNS uses.

Do the DNS requests show up in gatekeeper as

DNS: lookup for xxxxxx

or

NAT: UDP connection to xxxxxx:53

?

Adrien

The first one:
DNS: lookup for xxxxxx

Hmmm

Do you have the windows firewall enabled on these connections?

That can mess with things, since it translates port numbers. WinGate has a built-in firewall, so there's normally no need to run the windows one as well, as long as the wingate one is enabled, and your external adapters are set as external.

[Maxsit]

No, I don't use any firewall. I don't use WinGate one also.

[adrien]

You're brave!

Most ISPs now, if you don't have a firewall running, due to the number of other infected users, will give you a virus within about a second.

when's the last time you did a virus scan on that machine? Some viruses can play havoc with your networking.

I'm not brave. Firstly, how can I use firewall if ENS blocks an internet access? Secondly, I have up-to-date WinNT 4.0 SP6a + SRP + I don't have public IP address. Of course, I would like to resolve this issue and turn on WinGate firewall.
