Hi,
I have an issue with a RED 15w device connected to a SG210 UTM running firmware 9.602-3 which I am hoping someone might be able to suggest what setting I am missing. I will try provide as much info as possible and while I do know my way around the UTM and basic networking, I’m far from an expert.
The RED device is set up and functioning meaning computers behind the RED can access all areas of our main LAN in the head office. The issue I am experiencing is that computers on the main LAN (behind the UTM) cannot access devices at the remote site behind the RED. There is no visibility of anything behind the RED and I cannot even ping the RED or any devices attached to it from the main office.
I have the RED setup on the UTM and have added details of the RED to the following sections on the UTM: Interface, DNS, DHCP, Masquerading, NAT, Firewall and even Web Filter. I have attached images of all of these settings – I have blanked out our external IP and that but I have left our internal IP range as it is just used for testing and might allow you to see more information.
Just to add one final bit of information, here is where it gets unusual that if I connect my laptop to our network remotely via Sophos SSL VPN (whether I connect this way when I am on the internal LAN or an external connection) I can ping the RED and all devices behind it. I do however still have issues accessing shared folders on a computer behind the RED. I have attached this error as the final screenshot.
Any help or suggestions would be greatly appreciated.
The image uploads are:
01 – Main RED setup
02 – Interface settings
03 – DNS entry for RED
04 – DHCP server settings for RED
05 – Masquerading rule for RED
06 – NAT entry for RED
07 – Firewall entries for RED
08 – Web Filter entry for RED
09 – Error while trying to access shared folder when connected to network via Sophos SSL VPN
Kind Regards,
Niall
