Hello,
I'm using Zentyal server like gateway+office, that's the situation:
router Telecom (192.168.1.1) <---> Zentyal eth0 (192.168.1.100) external
router Tiscali (192.168.0.1) <---> Zentyal eth1 (192.168.0.100) external
switch Asus <------> Zentyal eth2 (192.168.2.100) internal
I'm using 2 ADSL in load balancing, and my LAN's addresses are 192.168.2.0/24.
All worked correctly since today I've configured on eth2 the DHCP module, to assing in auto ips 192.168.2.1-50 to a group of PC postations.
First problem: when I connect some PC's to the Switch, i try to obtain the IP by DHCP from zentyal, but it cannot obtain this and pc get an ip like 169.164.....
The only cause that can I thought is that each router's (tiscali and alice) have a proper DHCP service, that I can't stop (blocked router from providers), so when a new pc try to discover a dhcp , it has some problems from those 3 dhcp service....
Second problem: after some times I've activated DHCP, eth2 (the interface who manage internal network) of my Zentyal server logged in DHCP and results in the list of leases, losing his originally and static IP 192.168.2.100, and he got 192.168.2.1!
Look:
DHCP leases
IP address MAC address Host name
192.168.2.1 00:1c:c4:5f:6e:36 doss-srv
How can is possible that the server is using his DHCP ??
I hope someone should help me to understand,
Thanks a lot,
Lorenzo
