I can post 'show run''s if needed, packet tracer file is here for download Mega File Upload - 4.pkt I probably have completely messed up the switch vlan configs but please help thanks My understanding of the "ip helper-address" command is that in my situation i need to put is on the fa0/0 interfaces of my routers and using the address of the connected serial OR switch vlan address i dont know, And on my router 2 (middle router) so the serial interfaces need ip helper-address commands and if so what ip, the switch vlan ip? i have also tried making the switch router connection on its own vlan and trunking it, but it was that same result as i have just mention, everything can ping each other but dhcp never works. things to note, everything can ping everything (if pcs using static address) one thing i noticed is that i cant ping the switch from anything besides the connected devices, and i think its may be the problem. I need to set up the switch as dhcp server that needs to address ips for the 3 different lans, i was able to set up dhcp working for the 10.9.0.0/24 network however i cant get it working for either R1 or R2 networks, ive tried 'ip helper-address" commands many times but never worked out.
