>Description:
      User-PPP over an ordinary analog modem stops receiving packets after link throughput is continuously larger than around 4 kb/s (33600 modem) with setiathome running (nice 15). The problem is not modem specific, and the configuration is the default (no changes except auth info in ppp.conf). When setiathome is stopped (not sure if this is setiathome specific) the problem does not occur. The system also has IPNAT/IPFILTER compiled and is running as a gateway. Trafshow and tcpdump report only outgoing packets, however no packets are received and the physical line is OK. The problem might be related to IPNAT. -- When the machine was running NATD/IPFW combination previously, restarting NATD (refreshing the rules) would help. With IPNAT this is however, not the case.

>How-To-Repeat:
      Run setiathome and user-ppp together with a large download for a certain time period.
>Fix:
      See full description.
