[Openvpn-users] AIM Client Not Working POST #2

In the VPN server log I am seeing the error message:
MULTI: bad source address from client [10.0.2.2], packet dropped

 It appears that this only happens for chat data. http, ftp, email seem fine.

 When I do a tcpdump from the client machine the source IP for the chat
packet is on the 10.0.2.2 and all other traffic shows up on the correct
10.8.0.6 IP.

 Since I don't know what the client network is going to be I can't route
the traffic back to them.

 I am using the server config:
 push "redirect-gateway def1"

 I can see the routes are being added:
 Destination        Gateway            Flags    Refs      Use  Netif
Expire 0/1                10.8.0.5           UGSc        5       13  
tun0 128.0/1            10.8.0.5           UGSc        1        3   tun0


 When I run a tcpdump I see the wrong source address:
 10.8.0.6.64203 > a.ad.5446.static.theplanet.com.http
 10.0.2.2.64199 > 205.188.9.42.aol

 How can I get around this?
