Hi, I'm having problem adding DHCP service to my existing network. My laptop is getting priviate IP assigned when plugged into FastEthernet4/0/0, and I can ping them within network from my public subnet aa.bb.cc.0/20, but I can't seem to get out to the Internet from private subnet. Possibly a routing issue? Please help. Note: aa.bb.cc.0/20 is my public subnet, xx.yy.zz.48/30 is upstream provider, 10.1.1.0/24 is unable to brows.
