(2) Vlans, 30 for IP phones and 110 for workstations.
Pix 515E firewall - 10.0.0.10 / 255.0.0.0
Pix 506 firewall - 10.20.1.1 / 255.255.255.0
There is a vpn setup between the two Pix firewalls. I can ping from the home office 3750/Pix to the remote Pix 506 and vica versa.
I can ping from a host on the 10.20.1.0 network to the Pix 515/3750 switch, but not to any hosts on the 10.0.0.0 network. I also cannot ping from any host on the 10.0.0.0 network to the 10.20.1.0 network.
If I add a static route to a host on the 10.0.0.0 network pointing to either the Pix 515 or 3750 as the next hop for the 10.20.1.0 network, that host can then ping the Pix 506.
It seems like I'm missing something right in front of me.
One common application that requires helper addresses is Dynamic Host Configuration Protocol (DHCP), which is defined in RFC 1531. DHCP protocol information is carried inside of BOOTP packets. To enable BOOTP broadcast forwarding for a set of clients, configure a helper address on the router interface closest to the client. The helper address should specify the address of the DHCP server.
