15.7 Legacy Series / WAN gateway on different network
« on: October 17, 2015, 11:41:40 am »
I've just started using a dedicated server from OVH with ESXi, with an additional IP address. The additional IP address is assigned by ovh, and they also give a MAC address, which I have to set on the virtual machine running OPNsense (all of which is fine). However, the gateway you have to use for this additional IP address, *must* be the gateway of the network that the ESX host itself is sitting on. They explain it here: http://help.ovh.co.uk/BridgeClient
OPNsense doesn't allow a gateway which is not on the WAN subnet, so to make it work I added the following routing commands in /usr/local/etc/rc, immediately before the 'exit 0' at the end.
This now allows the OPNsense machine to access the Internet etc. However, a client on the LAN side of OPNsense cannot. Using tcpdump I can see the ping packets from the LAN client, hitting the WAN interface of OPNsense, but nothing after that.
Is there anything I can do to get this situation working?
Many thanks,
Steve

Code: [Select]
route add -net 12.34.56.78 -iface vmx1
route add default 12.34.56.78This now allows the OPNsense machine to access the Internet etc. However, a client on the LAN side of OPNsense cannot. Using tcpdump I can see the ping packets from the LAN client, hitting the WAN interface of OPNsense, but nothing after that.
