Hi.
I'm from Ecuador, my English is not very good. I hope you understand.
These are the general details of my configuration:
normal vlan 172.16.148.0/24
isolation vlan 172.16.153.0/24
registration vlan 172.16.158.0/24
The pf server have the interfaces:
eth0: 172.16.148.181/24
eth1: 172.16.153.1/24
eth2: 172.16.158.1/24
The interfaces are physical, each assigned to a port on the swtich Cisco 2960.
The problem: I have a proxy server running on another computer, to test the
proxy-bypass addon I install secondary proxy server on the PF server. The addon
works improperly. This addon redirects to the captive portal, but it takes the
IP address 172.16.158.1 instead of taking the node address 172.16.158.253. I do
not know if this is normal. I register with the address 172.16.158.1.
Upon completion in packetfence.log shows:
Jul
19 15:59:53 redir.cgi(0) INFO: 00:e0:4c:1b:ae:97 being redirected
(ModPerl::ROOT::ModPerl::PerlRun::usr_local_pf_cgi_2dbin_redir_2ecgi::handler)
Jul

registration disabled, freeing mac

http://www.packetfence.org/
(ModPerl::ROOT::ModPerl::PerlRun::usr_local_pf_cgi_2dbin_redir_2ecgi::handler)
But I can surf the internet. The firefox browser displays the following message:
"The page is not redirecting properly."
And the node continues with the address 172.16.158.253, is in the vlan
registration. If I do not use the secondary proxy server. PF is working
properly.
This is the configuration of the secondary proxy server:
#

# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports
# We strongly recommend the following be uncommented to protect innocent

#http_access deny to_localhost
#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#
# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks

http_access allow localhost
http_access allow localnet
# And finally deny all other access to this proxy
http_access deny all
# Squid normally listens to port 3128

ssl_bump allow all
# Bumped requests have relative URLs so Squid has to use reverse proxy

always_direct allow all
# we allow cert errors because of the nature of what we are trying to do
sslproxy_cert_error allow all
# we allow bad CN names because of the nature of what we are trying to do

# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /usr/local/squid/var/cache 100 16 256
# Leave coredumps in the first cache dir

# Add any of your own refresh_pattern entries above these.
refresh_pattern ^ftp: 1440 20% 10080

refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern . 0 20% 4320
#hierarchy squid
cache_peer 172.16.148.1 parent 3128 3130 no-query default
never_direct allow all
Thanks for the help.
Btw:
I need to configure the ports that connect swicth to eth0, eth1, eth2 with port
security.
