Captive Portal with Shorewall
.
"Saluton",
Sorry by my poor english, I speak Portuguese.
I does a captive portal using:
- shorewall
- dhcpd
- thttpd (in port 8080)
- maradns
With Shorewall I use dinamic zones.
The initial zone in shorewall is
configured to redirects access to
internal thttpd port 8080, that
shows a login.cgi page.
With thttpd I rewrite original url.
The apache rewrite is very cool, but

Per VLAN Bandwidth allocation by Shorewall
Hi,
1. We have 20+ VLANs behind shorewall firewall. We would like to distribute
the Internet bandwidth to different VLANs having minimumm, typical and
maximum values based on IP ranges after NAT e.g., 172.17.4.0/24. What rules
need to be created to do so?
2. We also would like to time the access of internet of some of the VLANs,
i.e., 172.17.4.0/24 should be allowed to access the internet only

Rsync rules for Shorewall
Hi folks,
I''m having an issue with rsync between my firewall and an internal
box. It seems to be a shorewall issue (or correctly speaking, an
issue with my shorewall config) because if I disable shorewall my
rsync works fine.
And I just can''t find it documented anywhere what I need to do.
I have rules like this :
root@userver:/etc/shorewall# grep -i Rsync rules

TCCLASSES vs Providers
Hi, I want to configure QoS in my shorewall conf but I have a doubt.

So, with this way I route my smtp traffic with my provider number 2.
Well, now I want to configure QoS with tcclasses and tcdevices, but if I do
that I need to use the MARK in the tcclasses

Shorewall & IFB
Hello Tom!
After i read and analyze some docs about IFB i decide that for implement
this feature in Shorewall not need more efforts (of course i may be wrong).
If we have 'ifb0' device then we must activate ingress discipline on real
device (f.e. eth2) and redirect 'egress' from it to 'ifb0'.
tc qdisc add dev eth2 ingress
tc filter add dev eth2 parent ffff: protocol ip
