Hi
At the moment my MX is connected to the ISP using PPPoE/PPPoA in bridging mode. It works fine, apart from where it doesn't work.
To address the most pressing issue - inability of MX to properly handle the flavour of multicast I have to use, I am introducing another security device ahead of the MX.
So, I have to change the MX WAN port configuration not to go to a modem but to one of the LAN ports on the additional Security Gateway.
- How do I configure the MX WAN port?
- Do I need to do anything to cope with potential double-NAT issues?
- Presently, all devices are on specific VLANs, with a separate management VLAN.
- What IP do I give the WAN port?
Or
- do I uplink to the new gateway using a LAN port?
presently
>> ISP >> modem >> MX64 >> MS220-8P >> devices
imminently
>> ISP >> modem >> new Gateway >> MX64 >> MS220-8P >> devices
I have upgraded to the latest beta firmware for the MX, so that I can use the NO-NATting option. But NO-NATting has to be turned on by support, I wish to avoid using this option until I have the proposed configuration hardware in place, then, hopefully, all I will need to do is change the NAT configuration NATting will only occur once at the new Gateway device.
I fear that if I have NO-NATting enabled ahead of having both gateway/security devices functioning in series, I will lose internet connectivity.
I would be hugely grateful for some guidance as to the best way of achieving this.
