Setup UTM with what Draytek would have called a Routed Subnet

i currently have a small block of IP addresses from Zen 8ips (5 usable ones) and i use the Routed subnet option on the DrayTek router which works great i just assign a real ip to my linux VM and it gets traffic routed to it as expected.

I want to swap my Draytek for a Sophos UTM (Home Edition) its running on a board with 2 Ethernet ports so one to go into the openreach modem (PPoE) and one for the LAN and into the LAN switch.

Can i set Sophos UTM up in a similar mannerto the DrayTek Router with a routed subnet on the LAN side, or possibly over a Tagged VLAN on the lan side as the servers are VMs and can be tagged in Hyper-V no issue.

is this what is called ProxyARP? after having read around a bit on the subject?

  • Just if it helps.. this is an extract from the Zen Draytek setup guide found here: https://support.zen.co.uk/kb/Knowledgebase/Vigor-2900-Series-Routed-IP?Keywords=routed+subnet

     

    Vigor 2900 Series - Routed IP

    Aim of this article:

    This guide is for people who have a block of 8 IPs (or more) from Zen and wish to configure the router for Routed IP.

    The Vigor 2900 will run in dual NAT and Routed IP mode allowing you to have some machines on Private IP addresses and others with Public IPs.  For more information on NAT and Routed IP see Related Articles.

    It then Just goes on to explain how to do it which is rather simple on this router..

     

  • Hi,

    you are comparing a simple nat/router with a complex security firewall.

    You cam setup your routes in the UTM and you will also need to create packet filter rules and MASQ/NAT rules.

    If the traffic is incoming then you will need extra rules and dnat/snat rules.
