In OpenWrt, I can setup almost any kind of interface in
/etc/config/network. But I haven't found a way to create an interface for the PPP "virtual interfaces" created by the pptpd daemon (PPtP Server).
Theses interfaces are usually called
ppp1 etc., and I'd like to access all of them by a single interface name and create a separate firewall zone for them.
I can manually add
ppp1 to the already existing LAN bridge, but when I create a bridge with static address and containing only the PPP interfaces, my router becomes inaccessible after reboot (and the logfiles are held in RAM, so no way to read what's going on there).
Clarification: I'm not trying to set up interfaces for PPtP client (that works fine even through LuCi), but for a PPtP server.
