Is UTM blocking my laptop

Hello,

If UTM really would block your device ... it would not recognize the device if you use another network interface.

Try to ping the subnet interface you connected to. (your def.GW)

Try to ping another UTM-Interface.

Try to traceroute 8.8.8.8

Check the corresponding logfiles (Firewall-log or WebProtection log)

Post the results here.

Hi and many thanks for the reply.  I am working with two laptops.  Both have behaved very strangely and one which didn't work earlier now does so I am not convinced the problem is with the UTM but the second laptop is still giving me trouble so I shall concentrate on the older one which I use for roaming testing.  I am using IBMT42 (32 bit) running Antix 19 (Debian based).

I have management subnet connected to switch and have physical access to ports on some subnets.  (others not physically nearby.)

I have a lan cable and can connect to these ports.  The NIC is set for dhcp. 

I can ping the def.GW for the subnet I first plugged into.

I can ping the def.GW for the second subnet after rebooting with copper plugged into new port.

Ashamed to report that traceroute does not appear to be installed on the T42 and since I cannot access the internet from T42 I cannot install anything.  I have "ip route" but it doesn't tell me much

I can see the Firewall-log but do not know what to look for, as  you can tell I am not a computer person.

Similarly I do not know what to look for under Web Protection. 

I would appreciate more help if you have time but my UTM is very new for me and nothing has been set up correctly.  I am learning as I go and have just about managed the subnets and their vlans on L2 switches. 

Regards,

Budge.

OK I didn't get a reply from my last post but have been trying to use the tools in the UTM and tried the Policy Help Desk.

I found that my attempts to use the Internet on the laptop are frustrated at the name service stage, ie I can ping the website I want but cannot resolve the host/domain name. 

The Policy Helpdesk tab allows me to try a Policy Test by requesting details of the problem internet connection and I am getting the message:-

Client not in allowed networks

This must be the cause of the problem but how can I remove the block please?

In spite of the message my problem has been in the resolv.conf of my own laptop so please forgive my alarm.

Not the UTM after all!!!

I am offline for some days ...

Great to see you solve the problem.

Thanks for the info.
