Hi probably you do not remember, so a short resume I got an access forbidden error on the client from the cache peer and the request coming from a transparent proxy between them, all squid versions are 2.6 The same setup is/was working fine with 2.5, sure that the new transparent options for squid 2.6 were correct So after letting it go for a long time I tried again and the error still persisted and as last option after some source reading I tried this acl peer src 127.0.0.2 into acl peer src 127.0.0.2/32 ooops and works So it seems that 2.5 accept src IP without mask specifier and 2.6 not would be nice to have it described in the docs anyway, my problem is solved now ...
