Question - Basic Network Setup

I have as connected at Home:

Mac (192.168.1.2) ---> Router2-ETH0(192.16.1.1) / SERIAL0 (172.16.1.2) ---> Router1-SERIAL0(172.16.1.1)/ ETH0(10.0.0.3) ---> Switch(10.0.0.10) ---> PC(10.0.0.2) and Speedtouch ADSL(10.0.0.1)

Scenario:

Mac can ping all through to 10.0.0.3 and go no further
PC can ping all through to 192.16.1.1 and go no further
this means that Mac and PC Cannot communicate directly.

What I need is to enable them to see each other? And also Allow mac to get to internet via Speedtouch.

Any ideas?
What info do you need from the routers?

I have RAR'd The visual Layout and the Show Run from the 2 routers.

Configs look pretty good -- You might try getting rid of the access-lists and the access-groups for troubleshooting purposes. Also, R1 should only have 1 default route. From the switch 10.0.0.10 can you ping something on the internet like 4.2.2.2 ?

Can you ping either PC or MAC from the routers? Just want to see if a possible firewall was blocking ICMP traffic that wasn't first initiated from either PC or MAC

Thanks for the quick replies,

No configuration changes done yet

I have just tried it again, Mac can ping PC/Win2k3 (10.0.0.2) and vice-versa so thats working..
Mac cannot Ping Speedtouch (10.0.0.1) though why I dont know

And also I would like to route Mac onto the internet via speedtouch (is there a firewall problem on the speedtouch maybe?)

The Model is thompson Speedtouch 510, i will read up as well on how to route through it or disable firewall etc..

Thanks

I think is no need to run rip and eigrp on R1 and R2 in this simple config...
R2 only needs

ip route 0.0.0.0 0.0.0.0 Serial0

and
R1 needs:

ip route 192.168.1.0 255.255.255.0 Serial0

also, PC needs a static route for 192.168.1.0 network, via 10.0.0.3, otherwise packets (ping) for Mac will be dropped by getaway (speedtouch)...
in order to access the internet from Mac, R1 have to forward packets to speedtouch:

ip route 0.0.0.0 0.0.0.0 10.0.0.1

and speedtouch have to NAT the 192.168.1.0 network also (simple way) or R1 must have gre tunnel capability (more complex)

Thanks alot

The changes administered to the routers are as followed (as you specified):

R1;
ip route 192.168.1.0 255.255.255.0 serial 0
ip route 0.0.0.0 0.0.0.0 10.0.0.1
(R1 can ping the internet now thanks alot)

R2;
ip route 0.0.0.0 0.0.0.0 serial 0

PC;
I added in the 'Alternate Configuration' of the NIC TCP/IP Properties
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default gateway: 192.168.1.1 (R2 Eth0)

The Mac can ping the PC and vice-versa (i love that word)

Thanks alot, I do need guidance when I bang my head against the wall.

I am working on something else now, so I'll Be Back (as arnie said), for more help.......

Cheers
