routing and ARP questions
I'm still trying to set up my network. The devices that concern me at this stage in the set-up that i want are:
Here is the output of netstat -rn on OpenBSD:
nternet: Destination Gateway Flags Refs Use Mtu Prio Iface default 192.168.1.254 UGS 0 0 - 8 xl0 127/8 127.0.0.1 UGRS 0 0 33200 8 lo0 127.0.0.1 127.0.0.1 UH 2 0 33200 4 lo0 192.168.1/24 link#1 UC 1 0 - 4 xl0 192.168.1.66 127.0.0.1 UGHS 0 0 33200 8 lo0 192.168.1.254 00:24:17:f7:d5:88 UHLc 1 41 - 4 xl0 192.168.2/24 link#2 UC 1 0 - 4 xl1 192.168.2.77 34:15:9e:2e:0b:ac UHLc 0 23 - 4 xl1 224/4
What i'm trying to establish is whether the border router/ADSL box(which is a home router) Won't allow anything from interfaces that are on different subnets to it's internal interface, or whether i just haven't configured routing properly on OpenBSD.
A tcpdump sniff of the OpenBSD boxes external interface, while i'm trying to ping the border router from the LAN just revealed that OpenBSD's external interface was sending the icmp echo packets out. The only other thing mentioned in this sniffing session was that the ADSL/border router did an ARP request for the host on the LAN that pinged it. No reply was received. I can ping either the external or internal interface on the OpenBSD box from hosts on the LAN. I just need to establish whether it's the ADSL box/border router that is refusing to deal with packets that have source I.Ps that are not on the same subnet as it's internal interface/dhcp range or whether there is anything i can do on OpenBSD to improve the situation?.
btw when i did:
#route add 192.168.2.77 192.168.2.12
Thank you for your time and any replies.
