As we've been having some problems with sporadic packet loss, I've been preparing a replacement router (also an SSG5) for our current Juniper SSG5. I've setup the new SSG5 identically to the old one.
We have a /29 IP range with a single IP setup as a MIP map to a server and two others being used for VIP maps. Each VIP/MIP is accompanied by relevant policies.
Long story short - we tried connected the new SSG5 and some things were not working as they should. No problem, I just reconnected the old one. However, some things are still broken, even when I reconnected the old one. I fear I may have inadvertently changed some settings while browsing through old settings in my attempt to reconfigure the new SSG5 unit.
All inbound traffic seems to work as expected. However, the 192.168.2.202 server can't initiate any outbound connections. It works perfectly on the local network, but any pings or DNS lookups to external IP's fail. The MIP & VIP map to it works perfectly - I can access it through HTTP and RDP without issues.
Any tips on what to debug, or where I've messed up my config?
I've attached the full config here (with anonymized IPs):

Update:
Just as the problem seemingly arose without me having changed any config settings, it disappeared as well. I left the office at 9PM last night, not having found a solution for the .202 server not being able to access the outside. When I showed up this morning, it was working again - and nothing had been touched since I left.
Could this be a matter of connections timing out, new DHCP leases or something like that? We'll be trying to reattach the new SSG5 once again tonight - this time I'm thinking it might actually work, but we're running into the same time-based issues.
