Cannot access web from server console when firehol has transparent_squid set
I'm trying to set up an intercepting proxy and web filter (squid+dansguardian is the plan), using firehol for firewall configuration, on Ubuntu Karmic.
My squid.conf is:
Code:
acl all src all
acl manager proto cache_object
acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8
acl sahaara src 192.168.54.0/24
acl SSL_ports port 443 # https
acl SSL_ports port 563 # snews
acl SSL_ports port 873 # rsync
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 # https
acl Safe_ports port 70 # gopher
acl Safe_ports port 210 # wais
acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl Safe_ports port 631 # cups
acl Safe_ports port 873 # rsync
acl Safe_ports port 901 # SWAT

and my firehol.conf
Code:
version 5
sahaara_ips="192.168.54.0/24"
transparent_squid 3128 proxy src "${sahaara_ips}"
interface eth0 sahaara src "${sahaara_ips}"
policy reject
server dns accept
server dhcp accept
server http accept
server samba accept
server icmp accept
server all accept
interface eth1 internet src not "${sahaara_ips} ${UNROUTABLE_IPS}"
protection strong 10/sec 10
client all accept
server ident reject with tcp-reset
router sahaara2internet inface eth0 outface eth1
masquerade
route all accept
router internet2sahaara inface eth1 outface eth0
route ident reject with tcp-reset
The client computers access the web through the proxy with no issue. But the server console cannot, though it can ping and DNS lookup.
What's going wrong? |
