Hey there,
Thanks for the reply. I understand there is a bit of an issue from that regard, so I was trying to work around it. Normally I am routed a subnet as opposed to being directly connected, but this ISP is a bit... different with their policies.
Regardless, proxy arp would have solved the problem but it is in packet mode, and proxy-arp is a NAT feature, however I did find that I could allow unrestricted proxy-arp on the interface in question, and that allowed the model to work.
Like I said, this is only temporary and I am just playing with this link until I get my subnet, but I wanted to be able to pass some traffic into a lab environment from outside over this connection.
Cheers.
