No access to LAN behind SonicWALL
Hi there, I hope someone may be able to point me in the right direction on this one:
We support 2 networks at College, one main multi Vlan'd multi domain curriculum/admin network and 1 tiny (1 server and 8 PCs) Accounts network.
Currently the Accounts network use our network for Email, Internet and File Share access through a SonicWALL TZ170.
I would like to be able to remote to their network for support through the SonicWALL and have set a static route on the main layer 3 switch for anything on their network 192.168.1.0/24 to go to 192.168.10.250/23 (WAN interface on SonicWALL).
For testing I've opened all ports from the ICT Dept vlan (192.168.10.0/23) through the SW.
I can try pinging a host on the Accounts network and I get an RTO.
I can check the logs on the SW and it reports that an ICMP request was dropped from my IP address which is weird as I've got all ports open.
Any suggestions would be magic :)
