Hi All,
Pleaase help me in configuring FC12_64 as DHCP & FW & GW to ADSL Internet.
I have:
- eth0 (xxx.39.189.92) connected to one port of the DSL router, eth0 configured with
DSN' of ISP
- eth2 (10.255.250.37) connected to the local LAN, eth2 configured with DNS' of ISP
- DNS' of ISP are defined also in resolv.conf
- named is running
- dnsmasq running for eth0 (connected to DSL router port)
- iptables running
- FW has dns ports (53) open
- FW has eth2 (to internal LAN) as trusted interface
- Internet is accessible in that box (via eth0), websites in internal LAN as well (via
eth2).
>From another box in the LAN:
> ping 10.255.250.37
responds normal way
> host
isp.com 10.255.250.37
doesn't respond
(in the 10.255.250.37 box the tcpdump shows requests coming in port 53, but they are
not forwarded to superior ISP DNS and SUGHUP1 to dnsmasq reports 0 requests
received/answered/failed/retried/sent)
My question is: What is it incorect in my configuratins?
Maybe you need to -
echo 1 > /proc/sys/net/ipv4/ip_forward
and
iptable -t nat -A POSTROUTING -s 10.255.250.0/24 -j SNAT --to xxx.39.189.92
