Hi Squid list,
I am facing a strange problem here .. there is a box with 3 IPs.
1. 192.168.10.1 (common gateway)
2. 192.168.30.1/24 (assigned via dhcpd to 210 users on LAN)
3. 202.x.x.x (downlink ip)
If i put 192.168.10.1 ip pool assignment via dhcpd then all works fine. Squid is blocking 192.168.30.1 IP pool so that after vpn authentication via pptpd (poptop), users get 192.168.10.2/24 pool IPs and their browsing starts. But when i use 192.168.30.1/24 pool, it doesnt work at all. Let me paste the dhcpd and other conf here:
[root@cable root]# cat /etc/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
subnet 192.168.10.0 netmask 255.255.255.0 {
server-name "x.x.net.hu";
# --- default gateway
option routers 192.168.10.1;
option subnet-mask 255.255.255.0;
# option nis-domain "x.x.net.hu";
option domain-name "buraak.net.pk";
option domain-name-servers 192.168.10.1;
option time-offset -18000;
range dynamic-bootp 192.168.10.16 192.168.10.254;
default-lease-time 345600;
max-lease-time 345600;
}
[root@cable root]# service iptables status

some squid conf---
acl mynet1 src 202.133.44.0/255.255.255.0
acl mynet2 src 192.168.10.0/255.255.255.0
acl mynet3 src 192.168.20.0/255.255.255.0
acl mynet4 src 192.168.30.4/255.255.255.0
acl vpnips src 10.0.0.0/255.255.255.255
http_access allow vpn
http_access allow mynet1
http_access allow mynet2
http_access allow mynet3
http_access deny mynet4
i would appreciate the solution with some examples in this scenatio. thanks.
regards,
KG
