Hi! I installed Sophos XG VM in my home and I'm testing it and probably will use it for my home net and lab. Sophos runs as a VM on my homelab server. I have 2 ubnets there: 1. 192.168.1.0/24 - called Outside wih FW WAN interface attached to it…

Hi, noticed this behavior: - XG configured for 3 DNS servers - on upstream device only those 3 DNS servers are allowed for XG - occasionally XG sends DNS request to many other DNS servers and these are denied by upstream device - issue on 18.5.1 and…

Couldn't delete the post, so am editing it. I figured out how to add the XGS as the DNS server: in DHCP, uncheck the box to use the DNS settings and set the interface IP as the DNS server.

Is it possible to setup 2 groups for SSL VPN where each group has its own DNS settings? I have 2 AD domains on my LAN and want to have clients for AD1 get the AD1 DNS servers and the AD2 clients get AD2 DNS servers. Thanks.

System Configuration: 2x XG125s in an HA Pair running SFOS 17.5.15 MR-15. We have two ISP connections feeding separate unmanaged switches which feed Two WAN ports on both units. (ISP->UNMANAGED SWITCH->WAN Port). This enables failover for ISP Failure…

[EDIT] I misunderstood how DNS queries to addresses like 8.8.8.8 are routed. They do go through the VPN tunnel. My question -- which I can't seem to delete, so I am rewriting -- had to do with wanting to make the XGS be my DNS server, through an SSL…

Hi All, I'm currently testing migrating from the SSL VPN client to using The Connect Client with ipsec. I've set everything up and can connect without issue. I'm also able to resolve devices within the lan, ping them, access resources but no matter…

Hi, i configured some clients in the network to start using the XG as dns server on saturday mid-day. After this you can see the memory usage ramping up, is possible that there is a memory leak? Fw is on SFVH (SFOS 18.5.1 MR-1-Build326)

HI, Since myfirewall.co stops working, I would appreciate if you can add the ability to add a custom option. If you cannot add that option, I would appreciate if you can add the entry for my provider joker.com/.../what-is-dynamic-dns-dyndns.html Th…

I am running the latest XG release and am finding that sometimes DNS resolution is stopping. The Firewall is responsible for DNS requests. The problem tends to go away on its own by just waiting or I can force it by restarting the DNS service. Any suggestions…

I found a few similar questions from different people over the years as to why their XG makes constant DNS lookups to huge amounts of domains with none of the posts having a useful answer. Unfortunately all those threads were locked due to age so I've…

Hi, Can DNS Spoofing be detected.

I recently added Pi-hole as the DNS server for Sophos XG itself, and I’ve noticed in my Pi-hole logs that Sophos XG is making a significant amount of DNS queries to various google.x addresses, such as google.de, google.com.pr, google.to, google.com.af…

Hello all, I am currently trying to configure Sophos xg to replace my Fritzbox. From problems with certificates, I have become aware that my DNS resolution for internal hosts and the xg itself is not working. Currently I have only a test client, which…

Wr have a brand new XG86w that we are connecting to Comcast. The comcast modem is in basic bridge mode. The problem is that about every 10 minutes DNS fails. We cannot ping anything from the firewall. I have tried comcast default DNS, Google DNS and OpenDNS…

I'm looking to use the built-in DHCP and DNS server on the Sophos XG on my "Main VLAN" but I don't want other VLANs to be able to do any nslookups for the host entrys. Today VLAN1 has it's own DHCP and DNS server and the other VLANs uses the Sophos…
