The problem seems to be in the attributes the home server returns to the freeradius proxy. When I reconfigured the home server to authenticate only and not to send any attributes whatsover, everything worked as it should. The attributes that caused the proxy to get into an infinite loop were:
Service-Type = Framed-User Framed-Protocol = PPP Cisco-AVPair = "lcp:callback-dialstring=" Cisco-AVPair = "lcp:nocallback-verify=1" Cisco-AVPair = "ip:addr-pool=main_pool" I will try to set up a filter for these attributes.
