Hi,
Is it possible turn on upnp for VPN users for dynamic NAT rules ?
User connect via L2TP, i tried do that but MT requires two interfaces and added ppp interface isn’t possible for a longer period of time
UPnP is require for p2p clients
Make static L2TP bindings and use them.
You should probably watch this video about how insecure UPnP is…

The presenter demonstrates his tools (that I assume he himself wrote) for exploiting UPnP and how easy it is to scan private IP ranges, and hijack remote routers as web proxies…
So do be careful with UPnP.
