SMTP not working after WinXP XP2 Upgrade

[jiandc]

Hello,

I noticed that after upgrading WinXP to SP2, the SMTP of wingate is not working/routing emails anymore. I changed the firewall settings of WinXP to allow port 25 (TCP & UDP) but still thesame problem.

What if you try adding the WinGate exe to the allow list rather than just the port?

Also, there is an incompatibility between WinGate's Gateway features (pre-routing) as configured on the gateways tab for a service, and XP's firewall, since XP's firewall translates source port numbers for outbound connections regardless of whether it needs to or not (i.e. it doesn't need to but it does anyway), this means the mechanism we use for pre-creating hash entries for routing and interface/gateway selection breaks.

So we recommend if you need a firewall on the WinGate machine, use WinGate's firewall.

I already allowed Wingate in XP Firewall prior to the Port.

Should I DISABLE XPs Firewall, we are behind a PIX firewall anyway.

Easy to test - try turning XP's firewall off. If SMTP begins working, then it's something related to XP's firewall and should be fairly easy to figure out then. If not, then something else in your config has changed to affect this and we'd need to look at other things.

If you're behind a PIX firewall and you have WinGate's firewall on, the odds of anything happening is slim.

Disbaled XP Firewall and still thesame problem.
Below is a part of the SMTP Log file.

Which version of WinGate are you using? Just searched through all your posts, but could not find anything to tell me that.

Also, Adrien just suggested that you try to connect to the host specified using telnet on port 25. If you can reach it, we know that the connection out works to that host.

[jiandc]

Hi,

we have WG5.2.3 bulid 901.
i tried to telnet<host>:25 but could not connect.

[Pascal]

Alright, now, from a command prompt run nslookup. Then, type a set type=all in the window that opens. Then type the name of the host (faxmail.com)

You should see something like:

Non-authoritative answer:
faxmail.com nameserver = jcs1a.faxsav.com
faxmail.com nameserver = dcs2.netmoves.com
faxmail.com nameserver = njs1.faxsav.com
faxmail.com nameserver = nys2.netmoves.com

faxmail.com nameserver = dcs2.netmoves.com
faxmail.com nameserver = njs1.faxsav.com
faxmail.com nameserver = nys2.netmoves.com
faxmail.com nameserver = jcs1a.faxsav.com
dcs2.netmoves.com internet address = 204.124.244.65
njs1.faxsav.com internet address = 165.251.8.64
nys2.netmoves.com internet address = 165.251.28.71
jcs1a.faxsav.com internet address = 209.67.18.65

This tells us that DNS is working from the client. (If you get the same type of response). Can you check that it happens?

As a side thought, you can upgrade to 6.0.2 - your 5.2.3 key will work with it.

[jiandc]

Hello,

I tried the command and got thesame response.

I also tried to upgrade our Wingate but during the activiation, I get the message "ERROR: The activiation file is invalid".

Hi,

I downloaded 6.0.2 build 1001 and tried to activiate. Only the VPN got activated but still had thesame error message with Wingate License.

With the previous 6.0.1, both license cannot be activated.

[Pascal]

Can you get a trial license activated?

If you check your WinGate folder, there will be a two files ending in .lic. What is the size of each of those files, please?

[jiandc]

I activtaed the license but still got thesame error. Pls see below.

I am still having problems sending emails via Wingate SMTP. Hope someome can share his/her idea on how to solve this.

Thanks

Hi

The fact that WinGate cannot connect to these servers, and you also cannot connect from the WinGate machine using telnet on port 25 to these servers means something is stopping you connecting.

Can you deliver mail to anywhere else? Are you able to connect to any other mail servers on port 25? Is it just port 25 that is blocked (i.e. by XP's firewall), or all ports?

Is it only connections to these hosts that fail, or do other connections fail as well? If it is only these hosts, are you sure they are even there and responding to connections?

Adrien

[jiandc]

Its ok now.
It was McAfee VirusScan Enterprise 8i blocking port 25 againts worms.


Thank you very much for all your responses.
