Hi,
I understand that you have a site to site tunnel between SA520 and other end.
Form you end you have allowed 10.23.x.x network to a few hosts on the other end.
Now you want to allow 175.31.x.x network from you end to access a same few hosts on the other end.
if the above senario is correct, then why are you creating a new tunnel. Just add the traffic in the interseting traffic. that is more than sufficient.
Hope this helps.
Regards,
Anisha
