Please help , i have a dhcp on 192.168.21.0/24 and pxe server on 192.168.1.0/24. Now i want to install hosts in 192.168.21.0/24 using this pxe tftp netboot on 192.168.1.0/24. My hosts in 192.168.21.0/24 are getting IP fine then trying tftp to 192.168.1.0/24 its timing out and there is no firewall in between these networks. I can ping across networks fine but i cant tftp netboot. What am i missing. My next-server on 192.168.21.0/24 is the IP of tftp on 192.168.1.10.
I have a cisco 1840 on 192.168.1.0/24 network and also another cisco 1840 on 192.168.21.0/24 network. The second cisco was there to add more other subnets, so it has 192.168.22.0/24, 192.168.21.0/24 and 192.168.20.0/24. So all these subnets connect to a unmanaged switches. Now on this cisco i have 4 wic ports, one goes to the extisting network - 192.168.1.253, then the other three 192.168.21.254, 192.168.22.254 and 192.168.20.3254. there is a cable from this cisco going to a switch in the 192.168.1.0/24 network
I can communicate across these networks , they can talk to each other no issues only this pxe i want to boot from 192.168.21.0/24 network. I am getting TFTP time out soon after a host gets dhcp IP.
