>Description:
Machine running as internet gateway (ipv4 only)
just one inet interface nfe0
used both for internal lan and pppoe connection to adsl bridge
ppp used for pppoe, again over nfe0, with nat enable
ipfw used with dummynet for firewalling and traffic sharper
I can send requested config on demand
- I have Internet conectivity
- pppoe seems working, nat included, even opened ports
- internal lan seems ok, both in and out
- traffic received via tun0 seems working
- In lan workstations have correct inet access
- In lan p2p working ok (bitcomet)
- transmission-bt working ok on server
But, traffic sharp doesnt work as spected
After all short of test, seems that:
- traffic from local lan to tun0 pass out without hit on fw rules
- after log enable, I can see ONLY local traffic xmit tun0
tested with/without tx/rx checksuming aids an tso, no luck
any clues are wellcome
>How-To-Repeat:
All sort of test done in fw rules, without any hit detected,
so I suspect traffic from lan is going directly to tun0
without hitting dummynet.
>Fix:
Well, this is not the case
