I'm encountering a somewhat odd behavior with my WiFi clients on my LAN subnet (192.168.3.0/24). WiFi clients aren't able to connect to my printer on this subnet (yet can ping the printer from the command line). Instead the printer utility times out. Wired clients on the same subnet are fine. Wifi (Mac OS X) IP: 192.168.3.110 Printer IP: 192.168.3.80 I'm running an ASUS Asus RT-N16 router with tomato only for a AP. Maybe it's something there, really not sure. (Tomato Firmware 1.28.0000 MIPSR2-140 K26 USB AIO) I have some firewall custom stuff, but this is for my other Virtual Wireless (VLAN) networks. Code: iptables -t filter -I INPUT 1 -p tcp -i br1 -m multiport --dports 22,80,443 -j DROP iptables -t filter -I INPUT 1 -p tcp -i br2 -m multiport --dports 22,80,443 -j DROP I've attached my topology diagram. I've captured some output from pfSense: Code: [2.4.2-RELEASE][email@example.com]/root: tcpdump -i vmx0 host 192.168.3.110 12:39:47.902133 IP 192.168.3.110.mdns > 126.96.36.199.mdns: 0 SRV (QM)?

Brother DCP-L2540DW series._pdl-datastream._tcp.local. (77) From what I gather these are bonjour requests... Any thoughts on what can be happening here? EDIT: I tried to enable "Enable Udpxy" & "Wireless Multicast Forwarding", still doesn't work.
