Cannot reach my TFTP server

[TS40]

Hello, I am working for an exercise related to NAT/PAT and OSPF etc.. . Everything works which should work apart from 1 small detail, I cannot reach my TFTP sever from my PCs and vice versa. Can anyone help me and possibly include the commands used? Thanks in advance

Hi @TS40 

  You need to add the  following command to the router R2:

router ospf 1

network 192.168.20.0 0.0.0.255 area 0
