Question: When trying to RDP from the 10.48.3.0 /24 or 10.48.4.0 /24 network it does not work unless you ping the IP first at remote loaction for example pinging 10.48.2.85 or any other machine on the 10.48.2.0 /24. I did put a static route on a few machines back to the Cisco (10.48.2.5 SGE2010) and those work everytime. Any Ideas?
I just figured it out, after doing packet captures the firewall was sending resets. I did an upgrade with another customer a few days ago they had problems with there remote sites when I upgraded there unit to 4.2. It was with the SonicWal...l Pro2040 firewall firmware v 4.2. I downgraded it and all the RDP connections work now without having to ping them first kind of odd?
I guess upgrading the other customer helped me figure it out, but I usually dont like downgrading unless last resort, so I guess messing someone up on last upgarde helped me get this resolved.
Can you please help us understand what Cisco router are you using in the network, this forum is mainly for small business router SA500 series and from the network diagram it is not clear. If you have some other Cisco router then we can forward to that post.
