VPN Policy-Based Routing + Web UI - ARCHIVE #1

I want to access my VDSL2 Netgear DM200 Modem from my PC through my LEDE WRT3200AC Router. DM200 is setup in Bridge Mode for the PPPOE connection to my ISP with the WRT3200AC doing all the login etc..

I have setup an Interface and Firewall rule as described in [SOLVED] How to access the modem (which is in bridge mode)? for my IPs and it works when OPR is Disabled but does not work when OPR is Enabled

I tried an entry in OPR for the interface name (DSLModem) of the DSL Modem connection but it is still blocked.

Setup:

WRT3200AC IP = Static IP 192.168.2.1
DSL Modem DM200 = Static IP 192.168.5.1
OpenVPN = 2 VPNs with both setup with "route_nopull" option so WAN remains the default route.
Static IPs assigned in the WRT3200AC for all connected machines on my LAN

Settings I changed/added that work (can access DM200 GUI at 192.168.5.1) when OPR Disabled:

Network Config:

config interface 'DSLModem'
	option proto 'static'
	option ifname 'eth1.2'
	option delegate '0'
	option ipaddr '192.168.5.100'
	option netmask '255.255.255.0'

Firewall Config:

config zone
	option name 'wan'
	option input 'REJECT'
	option output 'ACCEPT'
	option forward 'REJECT'
	option masq '1'
	option mtu_fix '1'
	option network 'wan wan6 DSLModem'

Has anyone got something like this working with OPR ENABLED or any ideas on how to get access to the DM200 Modem GUI working with OPR Enabled?
