This code start to work
===========
from gluon.sql import SQLCustomType

db = DAL('postgres://web2py:gfhj...@db.sibnet.su/test1',
pool_size=10)
inet = SQLCustomType ( type='string',native='inet')

db.define_table('firewall',
    SQLField('network',type=inet))
===========
Look like
==from gluon.dal import SQLCustomType
was not good idea.
BUT
Inserting or updating using web2py db admin
Shows following:
-------------------
Traceback (most recent call last):
  File "gluon/restricted.py", line 173, in restricted
