Proxy Agent subtree parsing

Hi Jochen,
Thank you for your reply.
I'll answer your questions inline :

Nope, I haven't any overlaped subtrees defined. Now I don't know if the
agent++ have his own objects within subtrees. I've tooked your examples
(snmp_proxy) and have modified for our needs. If you want, I can send you
my class.

I have no problems on agents with small trees, but if I check on windows
snmp agent or cisco routers it seems that after some tables the proxy agent
stop formwarding requests (as is mentioned in the log).

Do you know why my proxy agent stops contacting the cisco agent, although
it has forwarded all requests until 1.3.6.1.2.1.11.32 ? As I understand,
if I tell my proxy agent that the subtree 1.3.6.1.2.1 goes to the ip address
10.1.8.1, all requests within this subtree must be forwarded to this host

In you opinion must I use the old proxy object or go further with the proxy
forwarder ?
