So you have the wired and wireless networks bridged? Is the Asus doing NAT for you, or all NAT on the ADSL device?
Yes.The wired and wireless networks are bridged. Both networks are on 192.168.10.0/24. The WAN is separate on 192.168.1.0/24 (The interface actually has address 192.168.1.254 with default GW as 192.168.1.1 - i.e. the internal address address of my ADSL router). The ASUS also does NAT (so my internal network is behind two NAT routers.) The VLAN config (the default for the openwrt build) looks like this:
VLAN0 12345 ports together to form the LAN VLAN1 05 ports together to form the WAN
(where port 5 is the internal port). So any of the physical ports 1,2,3 or 4 or the wireless port are all on one VLAN and this is mapped to my internal network. I can confirn that this works because I can pick any single one port and/or the wireless and everything works as it should.
Is the dnsmasq server on the Asus, or elsewhere?
No. The dnsmasq is on a separate server (on 192.168.10.10). That dnsmasq server will issue (fixed) DHCP addresses to any of my wireless devices mapped in /etc/ethers. Other machines have fixed IP addresses.
DHCPing on the lan connection?
See above.
ICMP errors to where? Any problems with traffic between 2 wired hosts? Between a wired host and a wireless host? Between a wired host and a host in the DMZ? Between the wired host and the outside world? Or all of the above?
All of the above. Errors to anywhere. It is really weird. I can pick any port for the first connection and any (remaining) port for the second connection and that second connection consistently fails /unless/ I add another switch in the way.
I have no clue. :-(
