Hello! I am using shorewall for some years now, but i ran into trouble with the following multi VLAN setup: The network had two VLANs (vlan21 and vlan22) which are masqueraded by the firewall to a public subnet. vlan22 was running fine, but pakets on vlan21 did not get an answer. I setup another vlan (vlan23) to test so parameters, but that shut vlan22 down. Now vlan23 is working but vlan21 and vlan22 are not. I did some tcpdump and found out that the packets are correctly masqueraded and sent out but the response is not forwarded with the following errors: Jul 30 12:26:33 viegw kernel: [99036.969653] Shorewall:FORWARD:REJECT:IN=ppp0 OUT=vlan21 MAC= SRC=85.25. 182.38 DST=192.168.21.2 LEN=84 TOS=0x00 PREC=0x00 TTL=49 ID=31228 PROTO=ICMP TYPE=0 CODE=0 ID=2970 SEQ=55 Jul 30 12:26:34 viegw kernel: [99037.160452] Shorewall:FORWARD:REJECT:IN=ppp0 OUT=vlan22 MAC= SRC=85.25. 182.36 DST=192.168.22.2 LEN=84 TOS=0x00 PREC=0x00 TTL=50 ID=36303 PROTO=ICMP TYPE=0 CODE=0 ID=2964 SEQ=59 I have checked routing and config files but did not come up with a solution for days. Any help would be much appreciated! (i have attached a shorewall dump.)
