OBSD Help

Hello,

 

I could use some help getting poptop working on OpenBSD 4.9 with Apple iOS
devices. After much reading and searching I'm currently stuck. I can get an
iOS client (iPhone) to connect but when I try to ping the server I get no
reply. More specifically, when I do a tcpdump on tun0 I see my echo request
come in, I see the server reply, but the reply never reaches the client. If
I try pinging the client from the server, I see the server send echo
requests in tun0, but no reply from the client. It seems like traffic is
only going one direction in tun0.

 

I tried to add a static arp route but that didn't seem to help either.

 

This is the first time I've worked with OpenBSD and poptop so I could be
missing something simple. Any help would be appreciated!

 

Thanks,

J

doesn't matter to me if these need to be on a different subnet to make it
work)
