Subject: [dpdk-users] ip_pipeline firewall port filtering
Date: Fri, 17 Mar 2017 11:34:03 +0530	[thread overview]
Message-ID: <CAGSp03=ctU1vOd=HBYN8iQxMMaMXxLgAri7B+t5z3cmLHuCAKA@mail.gmail.com> (raw)

Hi

I am trying to just allow tcp dest port 80 packets using ip_pipeline
firewall, configured as under
------------------------------------------------------------------------------------------------------------------------------------

pipeline> p 1 firewall add priority 1 ipv4 0.0.0.0 0 0.0.0.0 0 0 65535 80
80 6 0xF port 0
pipeline> p 1 firewall ls
Prio = 1 (SA = 0.0.0.0/0, DA = 0.0.0.0/0, SP = 0-65535, DP = 80-80, Proto =
6 / 0xf) => Port = 0 (entry ptr = 0x7fddf9f0ff08)
Default rule: DROP
-----------------------------------------------------------------------------------------------------------------------------------

but it is not working and all tcp packets are getting dropped. If I
configure dest port range to be wildcard(0-65535) then tcp packets are
allowed

-----------------------------------------------------------------------------------------------------------------------------------
pipeline> p 1 firewall add priority 1 ipv4 0.0.0.0 0 0.0.0.0 0 0 65535 0
65535 6 0xF port 0
Prio = 1 (SA = 0.0.0.0/0, DA = 0.0.0.0/0, SP = 0-65535, DP = 0-65535, Proto
= 6 / 0xf) => Port = 0 (entry ptr = 0x7fddf9f0ff08)
pipeline> p 1 firewall ls
Prio = 1 (SA = 0.0.0.0/0, DA = 0.0.0.0/0, SP = 0-65535, DP = 0-65535, Proto
= 6 / 0xf) => Port = 0 (entry ptr = 0x7fddf9f0ff08)
Default rule: DROP

--------------------------------------------------------------------------------------------------------------------------------------

Has anyone got specific port filtering work with ip_pipeline firewall?
I am debugging this, meanwhile any help/guidance would be greatly
appreciated.

Thanks and rgds
Shyam
