tunneling through public IP destroys my network

I'm new to Zebedee, and tunneling for that matter, so while I have a problem, I'm not real sure which question to ask.

I set up Zebedee on a separate server, static IP, and then I set up a client machine.  On the LAN side of my router, that is when the IP address in the client is pointing to the zebedee server I am able to connect to my firebird database do my business and disconnect at will.  Seems to work good.

However, when I take the client outside the network and try to connect to the public address, I get a brief connection to the database (just the login screen) (though it seems to take to long to make the connection) and then I can't continue any further.  But here is the kicker.  After I make that connection, it throws my whole network on the LAN side into disarray.  None of the clients can connect to the Firebird database.

The database server and the Zebedee have a static IP address, but all the other clients are getting a dynamic IP address from the router.

The router is a Netopia 3346ent.  What we did on it was set up a server list that said any traffic on this public IP address on nnnnn port is to be sent to the private IP address of the Zebedee server.

From our ISP, we have 5 static addresses, the first useable is a.b.c.194 up to a.b.c.198.  I used the a.b.c.194 as the ip the client is trying to tunnel to.  this is the main address, would that cause it to mess up my internal network.

I dont know, maybe this should be a netopia question, but I have to start somewhere.

here is the client configuration file

verbosity 1	# Basic messages only

detached true	# Detach from terminal
server false	# It's a client
compression zlib:9	# Allow maximum zlib compression
include c:\zebedee\allam.key

#tunnel 3051:a.b.c.197:3050	#public ip  was 194
tunnel 3051:192.168.1.83:3050  #private ip 

here is the server config file

#
#  Config file to use on a Server running Firebird & ZeBeDee
#

verbosity 2	# Slightly more than basic messages
detached true	# free from console
server true	# Yes, it's a server!
ipmode tcp	# Operate only tcp
logfile         c:\zebedee\zebedee.log

compression zlib:9	# Allow maximum zlib compression
keylength 256		# Allow keys up to 256 bits
keylifetime 36000	# Shared keys last 10 hours
maxbufsize 16383	# Allow maximum possible buffer size
keygenlevel 2		# Generate maximum strength private keys
checkidfile 		c:\zebedee\allam.id

redirect 3050:192.168.c.d:3050  #Firebird port
targethost 192.168.c.d # Set up firebird server as the target

# end config file

I would appreciate any and all help on this

Thanks
