Trying to modernize dialin service here, using Bm3.7 RADIUS. But documentation seems to say BM3.7 cannot do the hardware access, only the authentication while working with a "network access server". Is that right, that I can't plug modem or multi-modem board into BM3.7/RADIUS server? If so, is there a list of "network access servers" known to work with BM3.7 RADIUS?
