We have a new Cisco 877 at our main office which has just replaced an old sonicwall pro100
There is a VPN which has been setup to a sonicwall TZ170 and seems to be functioning fine apart from the fact we cannot access ports through the VPN which are also forwarded from the external interface.
We only have 1 public IP so cannot terminate the VPN on another IP.
This use to work with the sonicwall, but have been unsuccessful with the Cisco. Is this possible?
Please let me know if you need to see the config or any other details and I will post
Thank you in advance
