following a breach of club discipline at Posh.
Peterborough boss Darren Ferguson has said he does not see a future for the forward at London Road.
"Obviously I'm contracted there so that is my parent club," Barnett told BBC Radio Suffolk. "But if I could get away I would be delighted."
Barnett's Posh exit came after he and winger Nathaniel Mendez-Laing, now on loan at Portsmouth, were
"There's always regrets because I didn't want to leave the club in the way that I did," he said.
"I'd rather it be on good terms. But that's life. You take it, get on with it and hopefully I can move on."
Barnett has said supporters at his new club should not base their perception of his character on the manner of his Peterborough exit.
"I'd say take it with a pinch of salt. The lads and people who know me know I'm not a troublemaker or whatever people want to come up with," he said.
"When you get to know me I'm an all right guy."
The former Macclesfield frontman switched to Peterborough from Crawley in a club-record £1m move in February and went on to score four goals in 13 games.
But, after netting just once in 10 this term, he hopes to contribute the goals Town need to haul themselves out of the Championship relegation zone.
"I want to play as many games as I can and hopefully prove myself at this level," he said.
"I'm fairly confident I can get goals. I just need to get a few more games under my belt, get to know the lads a bit better and I'm confident in my ability. It's got me this far."

Silvanos Mudzova, a member of the pressure group Tajamuka, said he had been abducted from his home in Harare on Tuesday night by unknown men.
He told the BBC he had been blindfolded and tortured with sharp objects.
He was also electrocuted on several parts of his body, including his genitals, Mr Mudzova said.
He said his captors had been armed.
The activist said his attackers had interrogated him, wanting to know who was funding his Tajamuka pressure group and why they were campaigning against President Mugabe's government.
The spokesman for the group was also arrested but granted bail on Wednesday.
Despite the latest government ban on protests in the capital, Harare, a massive demonstration has been planned for Saturday, according to Mr Mudzova.
Zimbabwe has seen a wave of protests recently over the declining economy.
Earlier this month, President Mugabe criticised judges who gave permission for anti-government protests which later turned violent.
He said the judges had shown a reckless disregard for peace and warned they should take care when making decisions.
The opposition has accused Mr Mugabe of trying to intimidate the judiciary.
Last week, Zimbabwe's high court overturned a two-week ban by police on demonstrations in Harare.
Activists who are opposed to President Robert Mugabe and his government challenged the ban in court.
The president recently warned protesters there would be no Zimbabwean uprising similar to the "Arab Spring".

The bank has previously said that a "significant percent" of its London workforce would be moved if Brexit became a reality.
The bank employs around 5,000 staff at its offices in London.
Earlier, the Lloyds of London insurance market said that after Brexit some of its business would move to the EU.
"We currently employ more than 5,000 people in London, and probably 20% to 30% of our workforce could be affected," the UBS chief executive, Sergio Ermotti, told the Japanese business newspaper Nikkei.
"We believe that London will continue to be an important financial centre, although maybe not as important as it is today," he added.
The UK voted narrowly to leave the EU in the Brexit referendum in June.
Since then the government and many UK businesses have been grappling both with the process of negotiating the divorce - which has not yet been formally triggered - and the eventual economic, social and political consequences of such a move.
Mr Ermotti said that it was too early for the bank to take any decision about moving its operations from London, but it was "well prepared" for any outcome of the impending Brexit negotiations.
Ipswich Town striker Tyrone Barnett has said he would be "delighted" if he never returned to Peterborough United.
