Hi all, install a shorewall 4 on a debian squeeze, configure the interfaces and the files, but I can not have internet on the local network. I can connect to the shorewall pc from outside and from the local network, I can connect to internet from the shorewall pc so I''m sure I have something misconfigured. ip route command throws me the following 192.168.2.0/24 dev eth1 proto kernel scope link src 192.168.2.1 xxx.xxx.xxx.0/24 dev eth0 proto kernel scope link src xxx.xxx.xxx.200 default via xxx.xxx.xxx.1 dev eth0 default via 192.168.2.1 dev eth1 scope link ifconfig eth0 Link encap:Ethernet HWaddr inet addrxx.xxx.xxx.200 Bcastxx.xxx.xxx.255 Mask:255.255.255.0 inet6 addr: fe80::219:d1ff:fedd:afd1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2374 errors:0 dropped:0 overruns:0 frame:0 TX packets:110 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:284690 (278.0 KiB) TX bytes:13739 (13.4 KiB) Interrupt:19 Base address:0x2100 eth1 Link encap:Ethernet HWaddr inet addr:192.168.2.1 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::227:19ff:feb1:6b69/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:204 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:17521 (17.1 KiB) TX bytes:468 (468.0 B) Interrupt:17 Base address:0x2000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:8 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:560 (560.0 B) TX bytes:560 (560.0 B) In shorewall: interfaces file: ================== #ZONE INTERFACE BROADCAST OPTIONS net eth0 detect dhcp loc eth1 detect bridge policy file: ============== #SOURCE DEST POLICY LOG LEVEL LIMIT:BURST #loc net ACCEPT #net all DROP info # THE FOLLOWING POLICY MUST BE LAST #all all REJECT info fw all ACCEPT all all REJECT info net all DROP info rules file: ============ #ACTION SOURCE DEST PROTO DEST SOURCE ORIGINAL RATE USER/ MARK # PORT PORT(S) DEST LIMIT GROUP # # Accept DNS connections from the firewall to the network # ACCEPT net $FW tcp 22 ACCEPT loc net tcp 20,21,22,25,43,53,63 ACCEPT loc net tcp 110,123,143,443,465 ACCEPT loc net tcp 587,993,995 ACCEPT loc net udp 43,53,63,123 REDIRECT loc 8080 tcp 80,8080 ACCEPT loc fw tcp 20,21,22,53,67,68,80,10000 ACCEPT loc fw udp 53,67,68 Ping(ACCEPT) net $FW Ping(ACCEPT) loc $FW Ping(ACCEPT) loc net masq file: ============ eth0 192.168.2.0/24 Hope someone can help me out with this.

I have had cases where Shorewall did not properly set ip forwarding to true, even though IP_FORWARDING=On was set in the config file. I never bothered to investigated, I just put echo 1 > /proc/sys/net/ipv4/ip_forward in my /etc/rc.local file and called it a day. But this was an old version of Shorewall. What version are you using? j On Thursday, October 13, 2011, Carina V.

Thanks for your reply. I am using Shorewall 4.4.11.6 and IP forwarding is set to 1 already: /proc/sys/net/ipv4/ip_forward = 1 Also for DNS resolution I had added following rules: ###Next 4 Lines for DNS Resolution#### ACCEPT loc $FW udp 53 ACCEPT loc $FW tcp 53 ACCEPT $FW net udp 53 ACCEPT $FW net tcp 53 Is there any limitation to add rules in /etc/shorewall/rules file ?
