 |Hello, I have a trouble with udprelay. Just after start all work fine, 
 |but after 10-15 requests I have that:
...
 |10/23 07:54:51.90 [7581] 0+0: willSTLS_SV: ServerFlags=600010
 |10/23 07:54:51.90 [7581] 0+0: VSocket CNCT/UDPRELAY *:* 
 |212.3.132.115:27015  = -1
 |10/23 07:54:51.90 [7581] 0+0: server_open(UDPRELAY,:0,listen=-1)
 |10/23 07:54:51.90 [7581] 0+0: server_open(UDPRELAY,:0) BOUND
 |10/23 07:54:51.90 [7581] 0+0: UDPRELAY start#32  [31](47) 
 |10.1.1.100:3047 > 212.3.132.115:27015

Hmm... the number #32 seems to imply the maximum number of UDP associations
in udprelay.c and

 |10/23 07:54:51.95 [7581] 0+0: No permission: 10.1.1.100:3048 > 
 |udprelay://3.132.115:27015
...
 |Why udprelay://3.132.115:27015?! I think it must be 
 |udprelay://212.3.132.115:27015

it seems that the first byte of IPv4 address is overwritten by the overflow.
I could reproduce the problem.  The overflow in this case is just by one
element but it could be three times at the maximum.
I will fix it as the enclosed patch in the next release. Thank you.

Cheers,
Yutaka
