Newbie here,
I've got a Zoom ADSL X7N that's a combo router and DSL modem. Zoom's firmware is Linux. I would like to move to openwrt to get loopback port forwarding going. I'm not clear if it's possible given the intricacies of booting/running these devices and what looks like a tiny bit of memory.
I've converted a few devices, but they were all well-known, well-documented so those were easy. This is not one of those devices.
This unit looks vaguely equivalent, but it's not clear what firmware I would try. I'm aware of the likelihood of bricking. http://wiki.openwrt.org/toh/d-link/dsl-2741b
If I'm missing something that helps, please just let me know and I'll post it.
########Just the facts:
