Zone Alarm and no internet ... (1 Viewer)

[Lord Ac]

Yellow hello!

I just murdered Norton from my computer and replaced it with AVG and Zone Alarm. All seems quite sexc on my computer now. HOWEVER, my other computer networked to this one (which has the cable net) now cannot access the internet (although it can view my computer files, etc) ....

When I installed the zone alarm is detected two networks and I put them on the trusted zone ...

Thanks,

Ac

I didn't like Zone Alarm for my network (running Kerio at present);

You need to allow all traffic to and from the other computers - somewhere in ZoneAlarm. That's the best help I can suggest without poking around in it. If there is a custom filters section, try adding a filter to allow all access to their IPs (Assuming your internal network IPs are static, not administered by DHCP).

 

[Lord Ac]

So you think I should drop Zone Alarm and get Kerio instead?

How do you find the other computers IP?

start-->my network places-->click on connection, i.p should be somewhere there

Apparently my subnet maskor ip, whatever, IS assignme by DHCP ... wat the hell doe sthat mean? It keeps changing? BEcause indeed the numbers that Zone Alarm has for my network and the actual numbers i see now are slighltly different ...

You are using a router of some sort? Your router assigns each computer on the network a unique IP address and the same subnet mask each time the computer boots up. The part of the router that does this is the DHCP server. If ZoneAlarm is getting confused because these values are changing, you should be able to configure your router to give the same IP to the same computer everytime.

I dont have a router!? I just have two computers, both on XP and using ICS ... the secondary computer can onl browse when this primary ocmp has zone alarm shutdown ...

Here is an attachment ... one of them is for my cable internet and is "connected, shared and assigned by DHCP", the other for the LAN and it is "connected and manually assigned"

Anyone know what the heck is going on?

Thanks,

You want to add the range:

192.168.0.1 - 192.168.0.255

To your trusted zone. And I don't know about ZA, but there may be an option to select "Running on Internet Gateway", like there is in Kerio.

 

[loquasagacious]

In the firewall section of zonealarm (between overview and program control) select the zones tab and as MedNez says add the IP range 192.168.0.1 - 192.168.0.255 and be sure to click apply.

Also make sure the Internet Connection Firewall inbuilt with windows (XP) is de-activated though that doesn't sound like a problem.

GRRRRR ... Ive done all you said and more and it SOUNDS like it should work but there is still no net on computer B. For the record, let my type out some numbers:

COMPUTER B:
IP Address: 192.168.0.236
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1

Computer A:
(LAN)
IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
Default Gateway: (blank)

(Cable net)
IP Address: 211.31.11.75
Subnet Mask: 255.255.255.0
Default Gateway: 211.31.11.1


So i tried to open ALL these IP addresses on ZoneAlarm and so it looks like it does on the attachment ....

The only other thing I can think of (if the above doesnt make something obvious to you) is that there is some option not correctly selected on this screen:

Thanks for any help guys. really appreciated!!!

Under 'Internet Connection Sharing', you have the wrong option selected.

"This computer is an ICS/NAT Gateway" should be ticked. You're not a client running off the gateway, you are the gateway.

 

[Lord Ac]

Thanks a lot.

After doing that, and also adding a few more ip addresses (gateway address, etc) into the trusted zone, now I have Zone on both comps and internet working fine on both as well.
